Crabtree hasn't done a whole lot in his NFL career to this point, as he has mostly been used in a reserve role behind Jermichael Finley after being drafted in 2010 out of Miami of Ohio.
In three seasons, Crabtree has amassed 18 catches for 302 yards and four touchdowns, three of which came last year. With the Buccaneers, Crabtree will have a chance to see some more time with a very unsettled situation at tight end.
Last season, Dallas Clark was the main starter at the position but certainly did not light the world on fire, gaining 435 yards and scoring four times.
Clark will also be 34 years old when training camp rolls around and is currently unsigned, so Tampa Bay may just want to go younger with either Luke Stocker or Crabtree seeing the bulk of the action.
