Yes mid-range jump shots are being phased out of the game, and I agree it's not a good thing at all, especially if the team doesn't have a strong post presence and/or good 3PT shooters. The mid-range 2 may not be the most efficient shot statistically, but those who excel at it make them a much more difficult player to guard (see DeMar Derozan, Shai Gilgeous-Alexander, Jalen Brunson, etc. in the NBA).
As a defender, I actually think a shot chart like Michigan's is much EASIER to guard for teams with a good rim protector or two. For example, if a guard takes at least one dribble from the 3PT line, it is really predictable that its going to be a drive to the rim and as a defender you don't have to worry about them pulling up from the mid-range and minimizes the player's threat as a "three-level scorer".
That's part of the reason why a guy like Acuff (who doesn't get to the rim all that much) is better on offense than Dercack (who is better at getting to the rim but has no mid-range or 3PT shot). Another guy is Adam Clark from Merrimack. Takes over 17 shots a game and only 2 of them will be 3's (a lot of mid-range shots), and he had a great game against RU.
So while RU should look to get to the rim more and improve shot selection, that doesn't mean they should be like Michigan and not attempt any mid-range jump shots.
