It would be easier to come up with what is right with this team, because what is wrong is a long, long list.
1. No identity- last year this team finished 93rd on offense and 153rd on defense and 109 overall per KenPom. For reference to be a tournament team and be rated in the 90's on either side of the ball, you need to be close to elite on the other end. Some examples from last year Boise State was 86th on offense, but 20th on defense, Miami (FL) got in at 19th on offense and 107th on defense. If you are as bad as Minnesota was on defense (153rd), you have to be absolutely elite on the other side of the ball to make the tournament. Iowa State was 171 (!) on offense but made up with it by having the 5th best defense in the nation and that got them an 11 seed. Similar story with San Diego State having the 167th best offense, but the 2nd best defense.
This year Minnesota is currently the 180th offense and the 127th rated defense in the nation and 153 overall per KenPom. So the biggest glaring issue is this program is nowhere close to acceptable on either side of the ball and just getting to not terrible on one side of the ball (say 65th?) still leaves them as a team nowhere near tournament contention. What type of team is Ben Johnson trying to create? What are the non-negotiables to be a Ben Johnson type player?
Also Minnesota is 350th (!) in tempo this year after being 285 last year. They are somehow playing even slower than last years team full of mid to low major guys. This doesn't impact their record, as some good teams play slow but being awful and playing a brand of basketball that would make Dick Bennett suggest you pick up the pace is the worst combination possible.
2. Terrible roster construction- Somehow Ben Johnson decided he didn't need to use 2 scholarships this year. That was despite losing basically 80% of his minutes played last year to graduation and knowing he was bringing in 4 Freshman and returning 1 Sophomore he basically refused to play the year prior (Thompson). We started this year without a legitimate option at the 2 guard. Freshman coming in ranked outside the top 100 like Henley and Carrington are not expected to start for Power 5 schools. For reference, Eli King barely gets off the bench at Iowa State and he has a similar recruiting profile. Ben decided Cooper was "his guy" at PG and brought him in with zero competition for that role. I wouldn't give up on him as a starter but it doesn't take Tom Izzo to look at him play at Morehead to notice that foot speed could be an issue defensively at this level. When you decide to pair him with a Freshman in the backcourt, that makes it very tough to defend the perimeter. The injured guys in Ihnen and Fox don't solve any of the problems with perimiter shooting or shot creation at the guard spots. Maybe Ihnen would have helped with the perimeter defense? Ben has certainly described a much different player in Ihnen that he was his first two years as a Gopher.
3. Lack of an edge- I never bought any of the nonsense about last years team of 1 year rentals creating some sort of culture for future teams to follow while finishing in last place. If you watched any of the Gophers against UNLV and turned the channel over to SDSU vs Arkansas you saw a completely different game. Forget the athletic differences, those guys were running harder, setting harder screens, fighting for boards, etc, etc. Payne is by far the Gophers best example of this, but sometimes his lack of experience limits his effectiveness.
A few quicker points as this is already way too long. Battle might be out of position at the 3. It was something I was slightly worried about coming in to the season. He had most of his success last year on offense playing the 4 or the 5. Is he quick enough at the 3 to still have a varied offensive game or is he just a jump shooter at that spot? He's still just coming back from injury so I might be biased towards my original hypothesis here. Starting Thompson is baffling. He has more of an interest in floating around the perimeter than doing the dirty work in the paint. For a team lacking an edge starting a Thompson/Garcia/Battle front court just magnifies that. That's a finesse lineup for a team looking to score in the 80's, but Minnesota doesn't play at a pace that makes that possible. Ben HAS to start benching guys for poor shot selection and/or lack of effort on the defensive end. I thought it was a problem last year when 2 guys in particular would have very notable lapses and nothing was ever done about it. This year we have guys who haven't had a shot in a couple possessions just decide it's their turn and take a contested jumper. It's the absolute easiest time to take a stand with those things in games you're down big (ex UNLV or Penn State last year) and he just doesn't do it.
