Contributed is the key word.
The problem is impact is what makes the difference in a team's success.
I was a Cooper Jr. guy, but I never thought he'd make that much of an impact as a rookie barring an injury to Adams or Puka and McVay creating packages for him. But, yes, he would contribute.
Bain is going to be a case study for the league given his historically short arms. I could never get on his bandwagon as I still believe he's better served as a 4-3 DE. That plus, when I saw a couple interviews where NFL OLineman pointed out how much easier it was to play guys with shorter arms.
But, most importantly, whenever I watched Miami I came away more impressed with Mesidor than Bain. Even on a couple of his sacks it was Mesidor who forced the QBs into his lap. Maybe I watched the wrong games, but he really didn't appear to do much during the season only to turn it on a bit during the playoffs.
