Okay, I personally don't think Spikes or Fletcher is the best Bills LB'er, so let me chime in on the old well Fletcher benefits from having Fat Sam and prior to that Williams in front of him. True, but how much does Spikes benefit by having Shoebal in front and Fletcher who is always at home next to him. Spikes can tee off and be everywhere because he knows Fletcher is there, he knows Milloy or Wire would tackle the guy if he missed. Yes I said wire. Because while the boy can't cover very well, he can flatout tackle and do run support. So Spikes benefits tremedously there.
To those underestimating Conlan or Bennett, don't. They didn't have the safety support that Spikes and Fletcher do. TKO and London can have a lot more free wheeling that those other two couldn't.
