Just some perspective on Ed Oliver. Let's compare him to another undersized former Bills DT, Kyle Williams after 4 years in the league.
Games Started: Williams 57 > Oliver 53.
Total Tackles: Williams 215 > Oliver 151..
TFLs: Williams 32 > Oliver 30,
Sacks: Williams 8 < Oliver 14.5
QB Hits: Williams 29 < Oliver 42
Williams received an early extension in July 2008 for 3 years at $14.4mm total. In 2011 he recieved another 6 year extension for $40mm with $17mm guaranteed.
I guess given the similar numbers in their first 4 years the Oliver signing is understandable. It was in 2010, his 5th year that Williams was named a Pro Bowl and 2nd Team All Pro. Might we see the same from Ed Oliver this year?
