This article was inspired by a comment from Atticus17, who listed ten backup players he was interested in following closely in this year’s training camp. I shortened his list to seven players, then added my thoughts about why I think these seven guys are critical to this season and beyond, despite the fact that most of them are unlikely to win starting jobs this season. Several are rookies; some are returning from injury. One entered the NFL as an undrafted free agent. Each should be a fascinating player to watch in training camp and the three preseason games.
