Dump law firm and pick up Tebow on the cheap. Use him as a running back that can catch out of the backfield. He's a big kid and a good football player. BB likes guys like that. I don't think they would even consider him as a QB. Who else would want him as QB?
I'm not convinced his ego will let him play anything other than QB. I just don't see him as being the kind of guy who's going to willingly play at a less-glamorous position.
But he really could be a great player as an H-back, kind of in Aaron Hernandez' role. Run the ball a little, but not as a primary running back. I don't see Tebow as a full-time running back; he's great with the ball in space, but I don't see him as being a great rusher between the tackles; too upright. But in an H-back role, get him the ball on some quick slants, get him some screen passes, maybe a couple rushes, he could do really well in that role. But, it's not the kind of role that's going to keep you out in front of everyone.
EDIT: He also had the third-most fumbles of any NFL QB last year, thirteen (in basically twelve games). Pretty much anti-Law Firm.
His rushing average wasn't spectacular in the second half of the year, either; the last six regular season games, he only had a rushing average >4.1/carry once (versus NE); the first six games, he was averaging 7.1/carry. It's not exactly comparable, his rushes from the option versus rushing as a traditional RB, but teams started figuring out how to stop his running game pretty quick (only 13 yards, on five carries, against NE in the playoffs).
