A couple weeks ago, Kliff Kingsbury talked about how he -- on the fringes of NFL rosters when he was playing -- wished the Alliance of American Football had been around when he was still a player. "There are a lot of young men who are close and just need an opportunity to show what they can do," Kingsbury said.

Now the AAF is done, closing up shop this week unexpectedly. If there was anything vague about it folding, the league put out an announcement Thursday saying all their players were free to sign with NFL teams. Kingsbury had said the Cardinals (like every team) would be "evaluating all the prospects" in the AAF. The Arizona Hotshots had a handful of players who had spent time with the Cardinals, like tight end Gerald Christian, linebacker Scooby Wright and wide receiver Rashad Ross, who led the league in touchdown catches in its truncated only season. (Adam Schefter reported Ross is signing with Carolina.)

When it comes to the Cards signing players right now, however, numbers are something to watch. There are 71 players on the roster, only 19 short of the 90-man offseason limit. The Cards still are scheduled to have 10 draft picks, and they normally sign anywhere from 15 to 20 undrafted free agents. As it is, it means the Cards will likely be doing some roster shuffling before camp anyway. (Draft picks don't count against the roster until they sign their contracts.)
