As mentioned the other day, the Cardinals still have a vacancy on their 90-man roster. Bruce Arians, during an interview on Arizona Sports, indicated that the Cards could still re-sign veteran running back Chris Johnson, which has always been a possibility as long as Johnson remained on the market.

With all that in mind, a quick look at the notable veterans General Manager Steve Keim has signed in the days prior or during training camp while the Cardinals are at University of Phoenix Stadium:

2013 -- T Eric Winston (started all season), LB John Abraham (led team in sacks), K Dan Carpenter (signed as competition to Jay Feely, lost battle.)

2014 -- T Max Starks (eventually released at end of camp), DT Tommy Kelly (had a solid season as a replacement for the injured Darnell Dockett.)

2015 -- TE Jermaine Gresham (has been team's top tight end since), C Lyle Sendlein (started all season), RB Chris Johnson (played well before late-season injury.)

2016 -- LB Donald Butler (released during final cuts), CB Mike Jenkins (was in line to start until tearing ACL).

Odds favor a couple more signings in this camp, necessary either because of play or injury. Whether they make a difference (see: 2016) we will see, but as always, the roster is churning.
