Easily? No way, but it's all opinion and hypotheticals, so we'll never really know. Moulds' career would probably be even better had he had the opportunity to play with one experienced vet QB during his tenure in Bflo like Butler and Lewis (after coming over from Pitt) did.
Lewis was decent in Bflo, probably better than he was in Pitt. He had a few good years, '81 being his best, but he was barely an above-average receiver at best when you take a look at his career.
Butler had 3 good seasons. The rest he averaged what, 15-20 catches per year? I wouldn't call that "terrific," but to each his own...
