I think Arias would have made the 53,.if the Cards didn't get Higgins on waivers...they are similar players/tweeners, IMO.Practice squad guys are always such a long shot, but I think Arias, Hayes, and Whiteheart may eventually earn some playing time this season or in future seasons. There's something to like about each one of them.
Not the worst signing. At least he has real game experience and has mostly been used as a 4/5th option...and logs about 20% of the ST snaps.
6th round pick, so he'll obviously never make it.
