ShovelPass is nice enough to post Snap Counts every Monday, so I went back and checked Kenny Young's Percentage of defensive plays per game; and the results are interesting.
Game 1 (Bears) ... 100% of the defensive snaps
Game 2 (Colts) ... 64% but this was the game he was ejected
Game 3 (Bucs) ... 100%
Game 4 (Cardinals) ... 99%
Here's where it gets interesting
Game 5 (Seahawks) ... 65%
Game 6 (Giants) ... 56%
Game 7 (Lions) ... 55%
So, Young was essentially playing every single snap on defense until the Arizona game; and then his snaps are cut-down significantly, and then further reduced. Seems like the Rams had quickly moved-off him.
I just hope the solution is not, like yesterday, more Reeder in passing situations.
