Player profile of WR J.J. Nelson as Arizona Cardinals training camp has opened As we have reached the second week of Arizona Cardinals training camp, we continue our annual look at the roster player by player. I look at what they’ve done, where they are now and how I project each player’s status at the end of camp. We go from A to Z and continue with WR J.J. Nelson. Nelson was drafted in the fifth-round of the 2015 NFL Draft by the Cardinals out of the University of Alabama-Birmingham. 2014 season: 38.3 yards.
