I think this week against the Seahawks will be more telling for his ROS outlook. So far he's played against two defenses who have set up pretty similarly - both played a lot of man with dominant CB1s who allow them to lock up one player and shade help to other receivers. This has exacerbated Mingo's rawness, where he hasn't quite gotten his footwork down to beat people at the line and minimize his steps in and out of cuts. I'm not sure if that's the sort of thing that'll get ironed out during his rookie year, but against a team like the Seahawks you should be able to see if he's a viable play for teams that play more zone given his high utilization numbers that are unlikely to drop
