I believe the Jags signing Tebow would be a great move for them. He has kept in shape, but even if he is mostly bench, it would be a good move due to ticket sales and his presence in the locker room. Lawrence is still young. He is a solid Christian coming from Clemson and Dabo. Having a more mature guy like Tebow there who has similar life values would be a plus for Lawrence. Anything that is a plus for TL has to be considered.
I think Trevor can handle any situation with very little help. The spot Tebow would take on the roster would maybe take away a real offensive weapon or more pass protection. Production on the field will help TL more than locker room(?) and moral support.
