I believe Beck has been #2 for some time.
A guy I work with is a friend of Beck's, and before the ISU game, supposedly, Cally pulled Beck into his office and told him that if Taylor was struggling that he(Beck) would go into the game in the second half.
As we all know, Taylor did phenomanaly well, compared to his previous performances, in the ISU game. Therefore, no Beck.
Of course this is just what Beck told my co-worker, so for all I know maybe Beck was just telling him that because he liked the thought of playing or something.
