Kyler Murray is going to throw the ball a lot, which means someone will need to catch it. And a large part of the Cardinals' training camp will be about finding out who.
Coach Kliff Kingsbury has already started addressing that. On Friday, he noted how he's used to playing eight receivers in a game, thanks to college rules, but he could imagine keeping up to seven on the Cardinals' roster. So for now, he'll move players around and avoid giving any concrete answers just yet.
It's too early to say, after all.
There are position battles all over the field, and the competition at wide receiver is not unique to the Cardinals this season.
