Seems like vossy is simply saying that lately Mitchell is shooting poorly. Not that he is a bad player or is a poor shooter. Just that he has been in a shooting slump recently. I think that is correct, and its ok. He has some reasons for it. He is a rookie (possibly hitting the "rookie wall"), defenses are gameplanning against him much better and he is facing better defenders and more double teams, he has been under the weather, the lineups have not been consistent and he has had to learn to play with different players (gobert came back, thabo went out, hood in and out, burks minutes all over the place, jerebko and jj minutes all over the place, Royce minutes increase, etc).......
I dont think anyone is really worried about DM at all. He is just in a small slump and even in a small slump he dropped a 40 point game, we have been winning all of the games, and he has mostly been productive on both ends despite his shots not dropping as much.
