Beyond the remaining holes at certain positions, there were two glaring weaknesses in the general makeup of last year's roster that haven't been addressed.
1. Speed - This offense and defense badly needed an infusion of speed. What did Keim do? He somehow made the team slower. Arnold wasn't a world beater, but at least he opened things up a little for the guys underneath. Nobody is worried about Max Williams going deep.. Reddick not only got to the QB, he could also run with most RBs and some TEs. Simmons can do some of that now, but outside of Simmons, the LBers are glacially slow. For a team that is supposed to play fast, we severely lack personnel with speed and athleticism, even more than last year.
2. Defensive playmakers - Peterson and Kirkpatrick have plenty of flaws, but they made plays on the ball. The current starting secondary has combined for 4 interceptions in the last two years. Hopefully Simmons can help out a little here, too, but he can't do it all himself.
To me, this team appears to have an identity crisis that has only gotten worse this off-season. Watching AJ Green get hit 2 yards behind the LOS on WR screens 3 times a game next year is going to be painful.
