From the video

they saw how good Gainwell played the most recent two weeks and the coaches were like, 'Oh, we actually didn't know he could do that.' Like they they may maybe there was like a lack of communication between the front office and between the coaches about why they even signed Kenny Gainwell, but they they were very impressed by what he has done the most recent two weeks. He has one target the most recent two weeks, but he is getting so much work on the ground because the team does not want to throw the ball.
STACKED’s take
Coaches impressed by recent play; ground-heavy usage limits pass-game upside
Gainwell impressed coaches with his play over the most recent two weeks; the source notes there was interesting coach speak where coaches said 'Oh, we actually didn't know he could do that,' suggesting there may have been a lack of communication between the front office and coaches about why they signed him, but they were very impressed by what he has done recently. Ranked at 39 for Week 9; not an ideal matchup against the Bears (who have been fairly good defensively), but usage has been heavy on the ground because the team does not want to throw the ball. However, he has only 1 target in the most recent 2 weeks, so the source wants him contributing more as a pass catcher.
