Whisenhunt has evaluated Kevin Kolb and John Skelton for two seasons. They've had all of OTAs, minicamps, and four preseason games. Both quarterbacks are sitting out the preseason finale. It is odd to think that the next few practices could decide things.
Skelton seems to be the favorite. He's been a little steadier during the preaseason. The problem, according to Kent Somers of the Arizona Republic, is that Skelton has often struggled during practice.
Overall, Kolb has reportedly outplayed Skelton in practice. Skelton has been better in the games. They don't keep score in practice, so this shouldn't be that difficult to decide.
