80 plays/game is nonsensical.
Reid was pass-happy. Incomplete passes and passes out of bounds stop the clock. You're adding a higher run-mix... running plays keep the clock moving. The Patriots averaged around 75/game with a killer o-line, superb QB, and solid RB in Ridley.
Where does anyone get 80? You're just pulling numbers out of the air with no justification.
McCoy is a beast, but let's be realistic here. The Eagles are likely to be trailing, Vick is a turnover machine, and they have Celek/DeSean as the only solid receiving options. McCoy has less upside to me than Richardson, Foster, Rice, Charles, or Spiller. Though, Spiller is close... his team situation isn't much better (and could be worse), but I think he's a more explosive player and has a better o-line.
Going by what I'm reading from beat writers. Not pulling numbers out of the air. I believe it was
Kelly himself that said he wanted to run a play like every 12 seconds.
Under Kelly, Oregon ran 1,077 plays in just 13 games last season (82.8 per game), according to ESPN Stats & Information. Amazingly, that would have ranked seventh (just two total plays behind the Eagles' 1,079) in the NFL's 16-game schedule last season. The
New England Patriots led the NFL with 1,191 plays last season (74.4 per game).
Kelly wants to run a play every 12 seconds, so he gets the Eagles ready for it in practice, even having assistants calling in plays via elaborate hand signals from the sidelines. The Eagles run a ton of plays, move around quickly and don't spend much time waiting, doing nothing.
