Pro Football Network named the Cardinals' top position battle to watch in training camp. It might not be a big battle.

They have plenty of cap space, should they want to make any additions before the start of camp. According to Over the Cap at the time this was published, the Cardinals have a little less than $36.1 million in cap space. That ranks fourth in the NFL.

The Arizona Cardinals are just over three weeks away from training camp. Football is almost here. Ahead of camp, the Cardinals still have some intriguing questions surrounding them. Despite how many questions were answered in the offseason, now is the time to see those answers manifest in a more tangible way.
