I wouldn't go down that road. For one, I don't think he's that much better than Tannehill. Plus, he'd cost a draft pick maybe a 2nd or 3rd rounder. He is one of those guys who has done extremely well in the postseason, but he is very inconsistent. Baltimore has taken off without him.
I think Miami should swing for the fences in the draft. On the draft forum, Kyler Murray has been discussed recently. He's the type of elite athlete that defenses can't really defense. Perhaps a better version of Lamar Jackson.
