if he can accept a backup or 3rd string role he will likely be signed by someone.

that’s apparently his issue, though, teams are interested in him if he would be willing to give up him pipedream about being an NFL QB.
Yup, he makes it pretty clear he won't be satisfied with a backup position. Nothing worse than a backup who is endlessly bitter he isn't starting. Teams know Tebow doesn't have the mechanics to build a franchise around him, but if he'd be willing to be a 2nd/3rd string QB who can maybe play TE in some packages he could have value.
