Jet's need "competition" at QB and Flynn is better than what they got or what they might get in the draft. Tebow is not a QB but he might be a great joker Tight End. And might add some more razzle dazzle to Hawk's trick play collection. Plus Seattle would finally get some media attention, but only if he comes as a non-quarterback. I don't know if team Tebow is willing to give up on football flinging but I think the rest of the league has.
I think keeping Flynn is still the best option for the Hawks. But a trade to the Jets might be the best thing for Flynn.
