Right on the money. Here's a guy in serious need of good coaching.
With Harmon, Chung, and McCourty all over 30, clearly getting younger at S was going to be a priority this off season. Think of this as just an early draft pick.
I don't see him having any impact on THIS year's team other than ST's depth. But it should jump start his off season by being here for the last 2-3 months of the season. And if, during that time, they find he's just another winner of the underwear Olympics who can't play football, there's very little downside.
On the plus side, he COULD end up being that LB/S hybrid I've been dreaming about for the last few years, that is IF they can coach up his "instincts" and football IQ to match his athletic ability.
