I saw this thread at the top, and thought McCline was already rejuvinated from yet another loss (Ruiz) and ready to get back in there. At this point, after so many disappointing losses in big fights (Valuev,Peter, Ruiz, back to back to back), McCline is probably pretty disgusted with himself and his future in the division.
Meehan would be the most entertaining fight, although I think McCline has the best chance of beating Golota on that list. Golota looks shot to me.
