I really appreciate Emshorts's sentiment here, so I am going to try my best to break down what I see for next year in terms of positives (obviously, this is all just my own opinion):
Offense:
1) Running Back - I don't see this being hugely different than it is right now, except for if the OLine improves. McCombs will be one year stronger and one year more experienced. The same goes for DeLorenzo, Hyppolite, and Joe Williams, where hopefully one of them will emerge as a solid backup choice if not better. Marriner comes in next year and will hopefully show his stuff. He will be young, so not much should be expected, but he's having a heck of a high school campaign. Overall, this area should improve, if only ever so slightly.
2) Offensive Line - I believe that this area will improve as well. Whether it's through the experience factor, or simply through a change of OLine Coach (I'll discuss that at another time in another thread), I believe that this unit will progress next year. Friend, Greene, Bullock, Mateas, and Cruz should all be better. Bennett is likely going to petition for a 6th year, due to all of his medical hardships, and that could be a very good sign as well. Samra, Rugg, Gifford, Bockeloh, and Levy will be one year bigger and better as well, so we should have some added depth to the line. This area should see a fair amount of improvement (if God hears my prayers), either through growth in the system or a return to our former system (you all know what I'm talking about).
3) Wide Receivers - There is talent here, and the majority is coming back. We lose Nick Williams who is versatile and fast, but who has also demonstrated that he has a difficult time bringing the ball in. We also lose Mike Smith, who has reliable hands but didn't have the "breakout" year that I thought he would. We return Phillips and Davis; the two receivers who I thought showed the most promise, and that's a good thing. We should see some more from Tebucky Jones and Ricky Gutierrez next year, and we may even get some early contributions from newcomer Dhameer Bradley or Noel Thomas, two talented receiver recruits. Overall, this unit should improve slightly to moderately.
4) Tight Ends - We're gonna take a hit here; there is just no way around it. You cannot lose two guys like Griffin and Delahunt and expect to be the same. The key people in this area will be McQuillan and Shortell. The question will be not just if they have the good hands that their predecessors had, but can they also help in the blocking the way that their predecessors did. Hopefully, the offensive line won't require as much help next year as they did this year; IMO a big factor in why the TE's weren't a bigger factor this year. This unit will likely show a drop in production moderately.
5) QB - Chandler will be one year better and one year smarter. I think that it should lead to a noticeable change in the TD to turnover ratios, and I believe that his QB rating will stay north of 120 if not better. Couple in the fact that Cochran has spent a year learning the system, and newcomer Lagow is on the way from Texas, and there should be a fair amount of competence here. McCummings will return also, primarily for the God-forsaken "wildcat" package. It's not a slight on the young man, since I think he is a superb athlete and I really wish they would involve him in either the pure run game or perhaps a slot receiver type deal. I think getting him the ball in open space can't be a bad thing. This unit should almost certainly improve.
Defense:
1) Defensive Line - We are going to lose a great one in Trevardo Williams. We are going to lose a really good one in Wirth. Joseph and Jennings will likely try to get an extra year (Jennings may not be able to, but I'm not sure). But we should still have some decent depth in this area. Stephen comes back, along with an improved Campenni, Willman, Pruitt, Norris, and Myers. We may also see Andreas Knappe begin to develop in this area as well. Possible contributions from Battles-Santos, Adeyemi, and newcomers Burlingame and Fatukasi. There will certainly be no "jaguars" in this group; there is a lot of size, even at the ends. I would say that this unit has a real chance to not show a lot of dropoff, but it will be difficult to get equal production without the speed of Trevardo.
2) Linebackers - We aren't going to be as good. That just seems to be unavoidable. You don't lose players like Sio Moore and Jory Johnson and expect to get better. However, there is certainly a fair amount of hope here. Smallwood is back, and Donohue will be a battle-tested senior next year (with plenty of experience in Don Brown's system), and transfer Graham Stewart (Florida) should factor in big here too. Marquis Vann should be pretty good as well, and we hope to see some people battling for game time, like Ashiru, Hicks, Steg (unless he goes DE), and perhaps even Clax (unless he goes to FB). Newcomers that may impress include Jasudowich and Junior Joseph. This unit may get slightly worse, but I believe that there is certainly enough talent there to make the transition less than painful.
3) Secondary - Ouch. Losing both Wreh-Wilson and Gratz is really tough, since they both have a legit shot at playing on Sundays. Taylor Mack is going to be one year better and has already seen significant game time, but he will have to improve his game to match either one of those we are losing. The safeties will be returning Adams, Brown, and Jones, so we should at least be slightly better in the back of the secondary. Wilbert Lee and Stephenson could be key to next year, and we will hopefully see contributions from Clark, Melifonwu, and Jhavon Williams, as well as possible contributions from newcomers Hadley and Lucas. We will likely be slightly worse in this area, but hopefully the experience at the safety positions makes the losses palateable.
Special Teams - Losing a returner like Nick Williams is going to be tough. Mack has shown some promise, and hopefully we will be able to find another speedster in this area to compliment Mack. Christen is back at kicker, so there will be a fair amount of experience there, with Puyol backing him up. Punter Cole Wagner will also be back, so special teams should not drop off too much overall, and in terms of kicking, should be even better.
Overall - Overall, I think there should be an expectation to improve, since I believe that so much rides on the QB and OLine on the offensive side of the ball, which means that the offensive production should improve a fair amount. I believe that the defense will still be very good, even if they cannot match this year's unbelievable performance. I believe that if we revert to schemes that favor the offensive line re-establishing the run (you all know what I'm talking about) and save Chandler from getting killed, we should almost certainly be in a bowl next year and I would have an expectation of at least 7 or 8 wins minimum. A very silver lining indeed...
