I thought it might be interesting to compare Holtmann's first 6 years on the job to Matta's last 6 years

Overall Win Pct - Matta 69.0%, Holtmann 62.1%

B10 Reg Season Win Pct - Matta 60.2%, Holtmann 53.4%

We all know about the lack of titles and deep tourney runs. So why? Why are the results as they are.

So from an offensive stand point, under Holtmann we are scoring about 1.19 more points/game than we did in Matta's last 6 years

BUT, we give up 4.12 more Points

Hence the scoring margin on average has shrunk from 8.83/game down to just 5.90/game

Hotlmann's teams shoot slightly better than Matta's team with an Eff FG% of 1.18% better

But, Opp Eff FG% has gotten worse, going up 1.59%

Some other little things that just seem to add up

Under Matta we averaged 6.67 steals/game, under Holtmann only 5.2 ie a nearly 1.5 fewer steals

Blocks is much the same story, Matta was 4.33/game vs only 3.65 now or a little over a half block per game less

Overall that means 2.22 fewer TO's created per game, combine that with the slightly worse Eff FG% defense and it leads to those scoring margin declines above.

Well what about rebounding then, Well the total Reb% has been essentially the same improving by less than 1% (0.35%) ie essentially a rounding error. 

So we shoot slightly better, score slightly more and reb slightly better, but at the cost of a fairly significant decrease in defensive efficiency.

Oddly on the offensive end we have seen a steady decline in assts/game. Overall the numbers between the 2 are fairly close with Matta slightly better at 13.35 vs Holtmann's 13.23, but the worrying trend under Holtman is the steady lowering of this number year over year.

14.7 to 14.1, to 13.3, to 13.1, to 12.5, to 11.7, that is a 20% steady decline in asst/game under Holtmann in 6 years. 

Note a couple other things. Matta's team played 12 ncaa tourney games while building these results going 8-4 including playing 6 games against teams seeded 8th or higher. Holtmann in part due to the covid year, has played only 9 such games going 4-5 with only 4 of those games against teams seeded 8th or better. Matta also has 2 NIT games to add to the competition that lead to those statistical results

All this leads to Matta having 4 of his 6 teams with scoring margins higher than 9.5/game, and Holtmann having zero such years.

Essentially, as the defense has fallen back from the Matta level's the offense has not improved enough and hence the margin for error has become much smaller leading to 7% fewer wins.

That may not sound like much, but we are again comparing the worst 6 year run under Matta to Holtmann, not the Evan, Oden, Conley led teams. And 7% more wins for Holtmann would be 16-17 more wins across those 6 years or nearly 3 more a year. what difference we may feel about this programs trajectory if that had been true..
