Thomson is p4p most underrated lw of all time. If guida can stifle Pettis, than Thomson (injury-free) can as well. Thomson has great stand up (getting better) and really good wrestling and jiu jitsu. I see him consistently taking pettis down and then eventually catching him in a scramble either with a good shot or a sub. Pettis has a chance to submit him, but I don't this will be contested on the feet.
