It looks like years 3 and 4 at Arizona were substantially worse than years 1 and 2. Year 1 was the best while year 4 was the worst.
”Johnson's fourth season in 2019 produced one of the highest-scoring offenses in the nation, a fourth-straight winning season, and a winning conference record. Arizona ended the 2019 campaign with a 32-24 record and a 15-14 mark in Pac-12 play. The club finished the year on a 10-game win streak and came away victorious in 13 of their last 14 games.”
Since the offense was high scoring, I assume the pitching was not so good.
At LSU he had Crews and bought White and Skenes. This year he didn’t make it out of the regional. In year 1 at LSU, they improved 2.5 games over the prior year. In the 2023 draft in the top 100 picks, there was Skenes, Crews, Floyd, Taylor and Morgan from LSU. As best I can tell, Skenes is the only one Johnson brought in. Looking at the numbers, it’s difficult to say how much Johnson positively influenced them, and you can throw White in there too.
