I'm just guessing based on the fact that they kept Jarwin and want to work in Rico, but I think it depends what Witten does. If Witten plays, they might consider cutting/trading Hanna for a conditional or a similar player at cut downs to get Rico on the roster if things go well in camp. Swaim does a lot of those same things. If Wit hangs them up, Hannah and Swaim become the starting combo, and Jarwin and Rico are the other two TEs for camp, with Rico getting a shot to steal snaps if he has really developed.
They do like Hanna, though. And they don't pay him so much that they have to agonize over keeping him if that's what they want to do. I like Swaim a bit better, anyway, though, and just want to make some room at the bottom of that TE group to keep Rico on the active roster.
