I guess this is what I disagree with. Even a disappointing 4th round pick should play 200+ snaps for you on special teams his rookie season, with the hope of contributing in sub packages for another 200+ plays his second year.
The problem with Logan Thomas is that if he doesn't/can't develop, then you're going to get 0 snaps from him and have to use a lower-round pick/free agent/veteran free agent to fill the role that you could have plugged a superior prospect into.
Just as an example--Alameda Ta'Amu was a 4th round pick in 2012. If Logan Thomas works out (a high-unlikelihood proposition in the best of circumstances--like 1 in 200), you don't even get that kind of contribution.
I don't get it. So how many snaps do you think the patriots second round pick get this year? Will he play on special teams?
