UFC vs. WWE: Top 20 Pro Wrestlers Turned MMA Fighters
Brock Lesnar is hardly the first pro wrestler to break into MMA. But you wouldn’t know that from watching the UFC vs. WWE buildup in the UFC 81 commercials. Brock isn’t even the first WWE Superstar to try MMA. UFC Hall of Famer Ken Shamrock leads that pack which includes Sylvester Terkay, Giant Silva, Ludvig Borga, Sean 'O Haire, and Bart Gunn.

So who are the top pro wrestlers turned MMA fighters? And where does Brock Lesnar fit in the all-time list? Here's my take:
