I'm with you, actually. If he played football with strength and power, I would just rail on his weight and frame as a fun joke, but not as an actual criticism. But his strength and size seem to go hand-in-hand here. As reference, Kiwanuka was in the 260s, and he never struck me as a strong player at the point of attack, particularly in the run game. Floyd needs significant time in the weight room.
Whether he puts on 5 or 30 pounds, he needs to be stronger to play in our defense, or otherwise we're spending a #10 pick on a weaker, smaller (but taller!) Mark Anderson with less collegiate experience at DE.
I see your profile lists BBI. I wonder what the collective mentality is there about Floyd.
