Ideally you have both. The speed and athleticism is what makes Avery Huff so intriguing. He may not have the polish Flagg has but once he becomes comfortable with the playbook watch out. Either way I'm optimistic about Flagg.
His deficiencies were straight-line speed and height. Very good in all other aspects. He'll at minimum contribute on special teams immediately and maybe earn second team reps by season's end.
I'm sure they're playing ok overall, I just hope it's more of ford/nesta making a leap vs the youngsters not playing well but I guess we'll see eventually.
