If you win two of the three phases - you can win games. SO that means if you win with defense and special teams, you can have a UCONN like offense and win close games. Not shootouts, but low scoring games.
Here is why I think Diaco went from not trying to win games in 14 to moderately trying to win games in 15.
In 14, Diaco claims he was building infrastructure and a way of living.
In 15, Diaco relied on his defense and improved on the offense - the QB was better(not Cochran), and we moved the ball better but could not finish off drives. The special teams started off abysmally and ultimately, we could kick extra points and field goals.
But here is why it is moderately, we don't try to block punts and we don't return punts. IF we actually set up blocks for punts and got let's say 10 yards every 4 th kick, that could translate in a shorter field and maybe at least an extra field goal attempt or even a touchdown as opposed to fg. My point is winning the game of field position is not just having your punter average 37 yards a kick with the return factored in. You have to help with punt return yardage, coverage, etc.
Randy Edsall, except for the Orlovsky years, relied on defense and special teams and look what he was able to accomplish. We couldn't throw the ball consistently, but we could run and we could defend and we had killer special teams.
I watched Poe from Army- who is slow, return a kick against Navy for 45-50 yards because the blocking was executed perfectly. I don't buy we don't have talent - we might not have 5* Madden types who can create on their own, but we do have athletes who can (as Hank Stram used to say) matriculate up the field.
In 16, Diaco better account for punt returns, because some of the close games can be turned by a little better field position. If he wants to win 8 games plus and a title, we have to be at least competant in all 3 phases. Rant over.
