I think he should fight Nick Diaz!
Diaz would present all kinds of problems for Penn IMHO.
He has great striking ability with a HUGE reach advantage standing.
On the ground he is almost as or as good as Penn is.
I would give Penn a slight advantage in takedown ability if anything.
TTT 4 DIAZ VS. PENN!!!
The reason why there are a lot of posts stating they want to see Lawler vs Penn is because I made this thread a couple of months ago before Lawler lost to Diaz.
