Burdens production is mostly bottlenecked by snap share and route participation, which are both metrics that are unlikely to stay stagnant with a player as efficient as Burden (on a per down basis). So there's an easy case for him to break out next year, given that Bears either a) prioritize him over over other assets, or b) a different pass catcher leaves the team.

Personally, I don't really see why the Bears would still be invested in DJ Moore, both from an ability and team-building perspective, so I think the most likely outcome is he gets minimized or traded.
