re: Will Tyrann still be the nickel guy next year?

I'm not sure that he will be able to be as aggressive in coverage or used in so many different ways next season unless another CB really steps up. Part of the reason that Mathieu could be so aggressive this season is that Mo could play the other teams best WR with no help. This allowed Chavis to do a lot of different things with TM7 and catered to his aggressiveness since he often had help on his side.
