Let me be clear. I was not someone who wanted Tarp on the original 53-man roster. HOWEVER, at present I think that he is valuable enough to be active this week and for the forseeable future. We need to limit the Special Teams play of our secondary. After all, most of them are playing with casts.
And, in the end, as long as Tarp performs reasonably well on Special Teams, he is likely to stay on the roster. It is not unusual for the patriots to have two LB/STers on the roster. We had Izzo and Davis together for four years.
