You've got an extremely liberal defintion of "wide open". The Patriots currently have seven TEs on the roster. Even if Gronkowski is out for the entire year and Hernandez is in jail, Tebow has no shot as a tight end.
um you realize that this thread sort of throws cold water on Gronkowski or Hernandez playing. So that reduces your all-star cast to:
Ballard
Fells
Ford
Hoomawatchamacallit
Sudfeld
