Delanie Walker, TE
This is the man Jim Harbaugh calls the Swiss Army Knife of the 49ers. Walker has returned kickoffs, played fullback, and even lined up at right tackle in a San Francisco uniform.
As an all-around athlete, Bill Belichick could certainly find a use for him. He had 21 catches for 344 yards and three touchdowns this season. He'll be 29 going into his eighth season in the league. And with the fluctuation in both Rob Gronkowski and Aaron Hernandez's health, he could be the vital backup or pinch-starter depending upon the situation.
