4. SP Colin Rea
The story of Colin Rea's contributions to the Brewers in 2023 is very similar to that of Teheran. The only difference is how they originated.
Some Brewers fans may not have remembered, but Rea had made one career appearance for the Crew prior to this season, a long relief outing in the second to last game of the 2021 season to help save some bullpen arms going into the playoffs. Back with the team in the minors in 2023, Rea was called up early this year for more of that rotation depth.
Though it wasn't always pretty, Rea ended up being an unsung hero for how he helped the Brewers navigate through injuries to the rotation. Yes, he has a 4.74 ERA on the season. But he also has a 6-6 record in 21 starts for Milwaukee and the team has a 13-8 record when he has started a game this season.
The decision on Rea's roster status is the exact same as Teheran's. The Brewers will largely be reliant on the Big 3 of Corbin Burnes, Brandon Woodruff, and Freddy Peralta to get lead the rotation into the playoffs with Wade Miley likely getting first crack at a start behind them.
Rea should be widely commended for how he was able to shore up the rotation this season. But he should not be on the team's playoff roster.
