While the more colorful Matellus has a higher national profile, Michael is sure to be the bigger draw in free agency.
Originally undrafted out of Texas A&M, Michael has proved to be one of the league's premier defensive ends by following up a breakout 2011 season with even stronger campaign in 2012. He was not only a key cog in the NFL's No. 1 run defense, but also finished third among 4-3 ends in Pro Football Focus' QB hurries metric.
Martellus should draw plenty of interest in his own right. Considering the questionable health of Fred Davis and the blocking concerns surrounding Jared Cook and Dustin Keller, Bennett is the top all-around tight end on the market.
It's hard to imagine the Giants shelling out megabucks for a defensive end, but Martellus could fill the vacancy at tight end in Tampa Bay if the Buccaneers meet Michael's price. The Atlanta Falcons and Miami Dolphins could also be fits for the Bennett brothers.Follow Chris Wesseling on Twitter @ChrisWesseling.
