WR Chase Claypool made his Bears debut this past Sunday against the Dolphins, where he caught two passes for 13 yards. It wasn't a particularly flashy start, but that was to be expected given he had been traded to Chicago just five days before kickoff.
It'll probably take a few weeks for Claypool to get up to full speed within the Bears' offense, so don't expect a sudden, massive uptick in his production. However, just having him on the field is a massive advantage for Chicago as Claypool is such a big-bodied receiver.
