The way I look at it is: He and the other players(but especially him) were extremely ANGRY after the loss. Not "disappointed," but downright pissed. They were pissed because they know how good of a team they can be with this roster, they know how important that game was, and they know they should have had that game locked up.
For all the analysts loving on Miami and claiming how good and "up-and-coming" they are, I think the Bills are going to go in there and clobber them. The Bills still won't get the proper recognition for that, but who cares. A win is a win. All the news will be about how Miami isn't as good as we thought they were instead of about the Bills being better than they thought they were. That's fine. Tannehill is going to get demolished. I'm sincerely questioning whether or not he'll be able to finish the game Thursday night.
