Strong wrestlers give Karo a hard time, but unlike the ones in the past who beat Karo (Sherk, St. Pierre, and Sanchez), they all had other things to work with: Sherk was already a veteran and I believe, then undefeated welterweight monster, St. Pierre has great stand-up and incredible athleticism, while Sanchez is very formidable on his back and with his submissions. Koscheck is, for the time being, strictly a wrestler, but one with incredible upside.
If Karo is able to improve his conditioning, his strength, and his takedown defense, then Koscheck is in for a rough night, because Karo is a talented, experienced veteran who has more tools to work with. His striking is better than Koscheck's and on the ground, even on his back, Karo is still a threat to submit Koscheck with something like an armbar or a triangle. And if Karo gets top position on Koscheck on the ground, I don't think Koscheck has enough experience or ability to handle Karo's GnP and submission game. I'll take Karo by exciting decision (or late round armbar).
