Dan Gronkowski

Lions TE Casey Fitzsimmons is the only tight end remaining from last year's roster and he's competing with three players that GM Martin Mayhew and HC Jim Schwartz have brought in - veteran free agent Will Heller and rookies Brandon Pettigrew and Dan Gronkowski.

Pettigrew, the 20th overall pick in the draft, will likely be the starter sooner rather than later, leaving FitzSimmons to compete with Heller for the No. 2 spot or Gronkowski for No. 3. Heller and FitzSimmons are different players so their position on the depth chart depends on what the team will be doing on any particular play. Heller is a good blocker with average receiving skills while FitzSimmons is a good receiver with average blocking ability.
