The Cardinals will begin the games that count Sept. 8, when they host the Chargers on a Monday night. From next week – when the players stream in for the beginning of training camp – until then, the roster will be formed through practice, roster moves, potential injuries and the like. With the pads on, there are still details to be worked out for the newest version of Bruce Arians' team. The first five most important questions facing the Cards were posted here already . Here are five more:

Unlike last season, when Rashard Mendenhall remained the starter all season at running back even as Ellington emerged as a potential star, Ellington is unquestioned at the top of the depth chart going into his second season. Still a question is how much he will touch the ball. Arians has thrown out the possibility of 25 to 30 a game combined carries and receptions, although that would be a massive jump over his average of 10.5 in 2013. Even with an expansion into a part-time slot receiver role, Ellington figures more likely to get to 20 to 22 touches. That's still a plenty big workload, but it would allow Jonathan Dwyer and/or Stepfan Taylor to carve out decent supporting roles. It's worth noting too that Arians last year made the point too much put on Ellington could be disastrous for the offense if he were to get hurt.
