What does rookie QB Justin Fields need to show? And what’s the most interesting position battle? 4 questions for the Chicago Bears heading into training camp.

Turning to the slot receiver position, if the Bears are going to become more potent offensively, they’re going to need more productive playmakers. Former second-round pick Anthony Miller was cast off to the Houston Texans, and since his arrival Damiere Byrd has been the logical candidate to join Allen Robinson and Darnell Mooney. Byrd had a career-high 47 receptions for 604 yards last season with the New England Patriots and has the quickness and speed to excel in the slot. Byrd could emerge as a nice signing. He won’t be the only option in three-receiver sets, and that’s where it is interesting because playing time will be up for grabs. Byrd should emerge ahead of Riley Ridley, Javon Wims, Marquise Goodwin, Dazz Newsome and others, but keep an eye out for someone excelling in the next several weeks. It’s also worth noting Byrd is probably best working in the slot, which is where Miller operated.
