Sounds like he came pretty close based on his late 2007 interview with Steve Cofield on ESPN 1100:

"I don’t think he’s going to have a future in MMA ... He’s a baby. Don’t kick him [because] he doesn’t want to get hurt. He’s a helluva wrestler and he’s strong. But he can’t punch and doesn’t know how to kick. He can only go straight forward. He can’t survive as just a takedown guy."

After watching former UFC Heavyweight Champion Brock Lesnar turtle under the striking of both Shane Carwin at UFC 116 and more recently Cain Velasquez at UFC 121 last Saturday night (Oct. 23), serious questions remain about Lesnar's ability to survive as a title contender when paired with heavy-handed strikers who can stay off the mat. Was Sylvia, who spent some time training with Lesnar prior to his UFC 81 debut, accurate in his assessment of the former WWE star? Or was "The Maine-iac" just taking potshots to keep his fading career in the spotlight?
