Guess I agree re bad if punt return team penalties extend drives, like the off sides early in game last week. Don't see anything as 100% yes or no. Opponent punting from own goal line, 4th and 9 (running into not 1st down), late in game and down 8; sure seems like time to attack. Also, only guys on punt return team that actually go after punter can't be more than 3 or 4 players, training them on how to attack block doesn't seem like such a hard thing to do. Also, pressure always increases opponent mistakes, getting them to "think" about what is coming, even if doesn't come very often can't hurt. Also, field the punts; if takes 2 guys back so be it.
As another note on special teams, if ball on kick off is coming down at 2 or 3 yard line if just get out of way and it goes past goal line (usually not like punt where might bounce back) it is touch back and out to 25 yard line. Also, never run ball out of end zone on kick offs (unless time and dire situation dictate otherwise).
When you are the 100th or so best team in country out of 129 you hit on every aspect of the game to get a little advantage. Special teams sure seems like an area to work at, it's not like it will take time away from starting DB's practicing their 10 yard cushion on 3rd and 8 pass defense.
