4. David Nelson has been a find
Speaking of players who went undrafted, how is it that this impressive 6-foot-5-inch receiver went overlooked out of Florida in the 2010 NFL Draft? Nelson said in a recent interview that the only two teams to contact him were the Bills and Patriots. He chose Buffalo because he felt like there was a better chance of him getting a chance to play. After making 31 catches in 15 games last year, a bigger opportunity arose this season after the trade of veteran Lee Evans, and he's taken advantage, with 14 catches through two games.
