 Usually, teams that run a 3–4 defense look for college "tweeners"—defensive ends that are too small to play the position in the pros and not quite fluid enough to play outside linebacker in a 4–3 defense—as their 3–4 outside linebacker.The wisdom of this strategy is demonstrated in the career of Harry Carson, who played as a defensive lineman in his college career and then went on to become a Hall of Fame ILB for the New York Giants in the 70s and 80s.According to NFL coach Wade Phillips, 3–4 linebackers "are a little bit cheaper, and you can find more of them," while "it's harder to find defensive linemen to play a 4–3 and pay for all of them."
