No. 2 reason 2022 will be better than 2021 for the LA Angels: More intel on how to use Shohei Ohtani
The LA Angels overall did a good job managing Shohei Ohtani's workload this past year. That being said, he did have to miss his last start of the year, as well as have another start delayed due to fatigue. He still hit every day, but there were a couple more starts we could have had out of Ohtani.
Now, however, that Matt Wise and Joe Maddon have a better idea of how to use him this year, they'll be able to potentially sit him from the batting lineup a few more days during the season, or maybe not have him play in the outfield after starts, and figure out that sweet spot where we can get the most out of Ohtani's talents on the mound.
Again, the Halos did a good job managing him this year. Some of the starts he missed had nothing to do with fatigue or a lack of durability (such as when he missed a start due to him getting hit with a foul ball in the dugout). The Angels will, however, be even BETTER with it next year, and that's something to look forward to.
