The progress of starting quarterback J.J. McCarthy has been the talk of training camp at TCO Performance Center. Whether the Vikings had a good practice or a bad one can often be reduced to how McCarthy performed in the heat of battle.

There have been conflicting reports coming out of the Minnesota Vikings' training camp on former Michigan star J.J. McCarthy. The reality is, McCarthy has a chance of being an above-average quarterback. The issue, however, and something that Vikings fans might not want to hear, is that he's coming off a tough injury.

The J.J. McCarthy era will begin on Saturday, as the Minnesota Vikings plan to play the quarterback against the Houston Texans in the team's preseason opener.
