I look Bauer as having produced elite seasons 2 of the last 3 years. I suspect 2019 was the outlier compared to his new true talent level. If he was hurt as he claims then he can have a pass for that season. I couldn't give half a f*** about what he did prior, that's not particularly important when players unlock new levels of performance in their career. Look at guys like Josh Donaldson, Jose Bautista, Edwin Encarnacion etc. as very good Blue Jays examples of players who reached new heights after many seasons of mediocre performance, and sustained that performance for many years afterward as well.
There may be a bit of a chance for somebody to acquire an ace level pitcher on a relative bargain contract compared to years past. Look at Stephen Strasburg for example, he received a crazy 7 year $245 million contract from the Nationals despite being older at the time than Bauer is presently. If somebody can snag Bauer with the MLBTR predicted 4 year $128 million deal that's a steal in comparison (admittedly looks very unlikely at this point). Bauer's best seasons are comparable to the best that Strasburg has managed to produce, and Strasburg has historically missed a ton of time due to injury. Projection systems actually appear to like Bauer more in 2021.
