Absolutely not Donaldson. He has almost become Adam Dunn, more XBH than singles and twice as many Ks and hits. He can still make some plays in the field, I agree, but it is not worth a season of his poor hitting. Power is nice but he does not really bring the power. He had about 70 PA and hit 3 HR, at that rate he would need over 450 PA to get to 20HR next season. The Crew only had one 20HR guy so that might seem attractive, but that is not enough overall production to justify signing Donaldson (who made over $20 million last year). Remember at a key moment in the first playoff game, a tie score, with one out and runners at second and third, Donaldson needed to put the ball in play. Any base hit or sac fly gives the Brewers the lead and he popped out weakly. He came up three times with men on in that game and ended up with 0 RBI. The 2015 Dondalson has left the building.
Of all the things the Brewers did well last year - pitching, defense, and picking up Santana, Canha, and Donaldson, and bringing back Miley - they were awful with projecting power bats. Tellez tried to play hurt for too long and his power suffered. The laundry list of DH/1Bs who were supposed to provide pop was historically bad; Winker, Ruf, Voit, Singleton, and Jones combined for 1HR this year.
This might have to be a semi-rebuild for the Brewers given the contract situations and injuries they face. Keeping a veteran like Santana who is a good clubhouse guy (much better reputation that Donaldson), who came in and helped several of the younger players develop patience at the plate (look at the number of pitches guys were seeing after Canha and Santana arrived, I believe they led the league), and as the original post mentioned, he will likely cost less than what the Crew paid Winker for this season.
The pitching is a whole situation to itself but on the hitting side the Brewers have lots of options in the OF, I'd like to see Taylor in LF, Mitchell in CF, Frelick in RF with Yelich primarily at DH but able to play in the field at times when you want to play match ups. You can have Perkins as a back up at all three positions and you can mix those guys a lot of ways. This gives you very good defense, excellent speed, and room for growth with the bats. With Wiemer and Churio at AAA to start there are options in case of injury.
On the INF, you have one of the best young catchers in the game, and you can bring Caratini back for arounf $3 million. Re-sign Adames at SS, Turang at 2B (if he can hit like he did in August he'd be about a 4.0 WAR), and re-sign Santana on a 1-yr deal at 1B. Then you need to go get a 3B, there is no in-house anser right now. Black might be the future but the Brewers need a proven commodity at 3B. I like Monasterio, he really stepped up all season, but he does not produce enough to be a starter at 3B, he could be the utility guy because he can play three positions and puts the ball in play.
This leaves the pitching and the pen looks like it could be good with Williams, Payamps, Uribe, Milner all solid returners. The starters are a concern, Peralta, maybe Ashby if he's ready to return, maybe they bring back Miley as a solid veteran presence. Houser and Rea provided some rotation depth and could again but neither seems like a must-have. I think they need to trade Burnes, it will be hard to get as much in return any other time and you cannot afford to let him walk for nothing after the season. After last year's arbitration hearing I think he will not sign a long term deal. You go in on Woodruff and hope he is the same guy he has been when 2025 rolls around.
The Crew needs a 3B and likely to new SP to combine with the pieces they have from last year, then they will need a manager that can guide them back to the post-season.
