The fight makes no sense for Nate Marquardt.
No. It won't happen for myriad reasons but specifically b/c:
Joe Silva prefers matching up two fighters who are either both coming off wins or both coming off losses. The caveat being unless one of those fighters is ranked extremely high or is an established veteran that can sell tickets. But the former is the most usual scenario. Thus was the reasoning behind Heiron/Silva.
Marquardt is a longtime UFC vet and champ of Strikeforce; fighting an unranked young prospect coming off a loss makes little sense.
If we were going to see Erick against a veteran I would surmise we would get Kampmann or Alves vs. Silva. But I suspect Erick gets a very winnable fight.
I think that Erick Silva would have to beat Hieron convincingly to get a shot at someone like Marquardt. Granted, Marquardt is not exactly proven at WW (he looked impressive against a decent wrestler in Strikeforce, but is yet to be tested against top-tier WW in the UFC). Bring Erick along slowly, maybe give him someone like Rick Story after Hieron.
EDIT: Didn't realize that Erick is injured and Hieron fight is off. Is Hieron getting a replacement opponent? If not, then they should reschedule that fight for 158.
Why do people keep saying Marquardt wants to FIGHT at UFC 158? He said he was looking to fight one of the WINNERS of the big ww 6 at UFC 158.
