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.

For the majority of the NFL's teams and their fans, the offseason is the biggest highlight of the seasonal calendar. Free-agent signings, draft picks and trades generate excitement and hope before the reality of the regular season (and possibly postseason) occurs.
