The problem with hanging onto him is that there just isn't enough spots for everyone. Yelich, Cain, Santana, Braun and Thames all deserve to be playing every day if healthy. Then you have guys like Phillips and Aguilar that arguably could be getting regular playing time. There's only four spots available. Even if you jettison Aguilar and say Phillips is your 4th outfielder, that's still 5 guys for four spots. If your answer is to platoon Braun and Thames, then you are taking one of the team's top bats out of the lineup every day. I'd be happy to keep him around too but think his best value right now is probably to use him to grab a pitcher. But if he is kept there's plenty of playing time for everyone outside of Aguilar. People have been saying this about the Cubs the last 3 years with Schwarber/Almora/Happ/Heyward/Zobrist/Russell/Baez and Fowler 2 years ago and Jay last year that they have too many guys and not enough spots but it ends up that everyone ends up getting their time and it makes sense in the end. Guys are going to get hurt, regress or just not be good. It's not bad to have depth and it's never bad to give guys more rest overall than having to play 150-155+ games not only to stay healthier but also optimize performance in the splits various guys have. Braun should probably be depended on for closer to 120 games than 140 games both in terms of how he's aging/getting hurt and keeping him fresh, Cain is 32 and we just made a long term investment in him he probably should be given adequate rest, there's going to be lefties you want to sit Yelich against, Thames should never play vs lefties, if Domingo is here you're going to want to pull him for defense and sit him vs some RHP, Broxton should only start vs LHP and be a defensive replacement, and Phillips is a bit of an unknown but has been a high K guy everywhere for the last 3 years so there's going to be certain types of pitchers to shield him against. And really neither of Broxton/Phillips should be depended on outside of depth to begin the year with intention to contend since they both just might not be good/platoon guys and if one guy has to play in AAA most of the year or only ends up with ~40 starts or being a late inning defensive/base running guy so be it, it likely means other guys are healthy and performing well.
