It may be. Belichek already has a back-up QB (Millet), so Tebow will be a third-stringer, if he stays at QB.
He's big enough to convert to TE.
Of course, along with the questions comes the sideshow that is Tebow.
Tebow is a team player.
Belichek is very good at handling high profile situations.
Both Gronk and Hernandez are hurt.
Tebow will be a TE, that's my bet. TE seems to be a position that an athlete can pick up in short order. Think Antonio Gates. Gates played basketball for KSU and was a very good pro TE.
I expect this will work out well for all involved.
