I don't think Kruger is worth $10 mil, but I do think he can play some ball. Last year he had 6 sacks and played less, splitting time with J.J and McPhee. Lets not forget who he was playing behind in 2011, double J was a lunch pale player. Lets also not forget the route they tried to take with Freddy, OLB to DE and back to OLB.
This year he had 9 sacks in the regular season and showed some great burst and hands off the line. Worth $10 mil? No, but completely fall off, I doubt it, he will post another 9-10 sack season and get some pressure on the QB.
