Yes, Jones played 113 out of 117 snaps at center over the last two games.
In my opinion, Jones had 3 good games (Western Michigan, Penn State, and Minnesota), 3 average games (Utah State, Purdue, and Tennessee), 2 below average games (Iowa State and Wisconsin), and 2 poor games (Michigan State and Michigan). He also played limited snaps at Rutgers (average), Northwestern (below average), and Illinois (poor). Overall, he was pretty average and not very consistent. Nobody should be claiming that he played "very well".
Elsbury had 3 good games (NW, Rutgers, Illinois) and 1 average game (Nebraska) at center. Smaller sample size, but he clearly outperformed Jones when given the chance. Hopefully Lester is able to start the best players, because I just don't see Ferentz benching Jones for Elsbury. I think that Ferentz really thought that Jones would become a poor man's Linderbaum and he would refuse to admit that he was wrong. You know, typical Ferentz stuff.
