Sonnen is coming across really well -- he seems genuine in his concern for his team mates, and his little motivational speeches are particularly nice. His team have managed to pull off a few good upsets, too!
Uriah is a bit of a nut bar. Maybe it's the house drawing it out of him, but he's a bit of a drag.
Barnatt's an interesting one -- hope he does well. We need fresh UK blood in the UFC after Etim and Mills both got cut!
