The opinions on 47-year-old former pro footballer Herschel Walker's recent MMA debut range from "amazing" to "disgraceful."

Count Strikeforce CEO Scott Coker among those who believe the Heisman Trophy winner was a good thing for the California-based promotion - even if he was admittedly unsure at first.

"I think the networks, at first, were apprehensive about Herschel, and so was I, honestly," Coker recently told MMAjunkie.com. "I was very apprehensive, but getting to know Herschel, and seeing his commitment to training at AKA and just who he is as a person and a martial artist, it was an honor to have him come fight for us."
