Look, it's simple. At the end of the season, Alonso is going to hit close to 35-40 home runs and will drive in 100+ RBI's. He's consistent enough to do that. Alonso plays everyday, Busch doesn't. I understand your reasoning in "cheap/team control" but I don't think it's what the Cubs need. You made the reference to Rizzo, which make sense, but Rizzo was traded in 2012 when the team was in full rebuild. No Cub fan knew what they were getting with Rizzo, but we were fortunate to see Rizzo/Theo's friendship paid off that started in Boston.
Rizzo was great defensively, but may have been a step behind Freeman (Atlanta days) and Votto when it comes to offensive numbers, I'm not completely sure. When it comes to Alonso, he may not be as good defensively compared to other first baseman, but he will absolutely be the best power bat in the NL Central, and will be protected due to Bellinger/Suzuki/Happ, etc. One thing about Alonso is that he's not getting protected at all in New York. He batted 4th over the weekend, and Starling Marte and Mark Vientos are hitting behind him. The Cubs today can't hit, but Alonso is a guy that the team could rally around when he gets going, and we've seen those types of strecthes.
You can give me numbers this and numbers that about Busch having a better season so far than Alonso. Unfortunately, I'm not buying it. Alonso scares pitchers and Busch doesn't.
Again, I understand your reasoning due to finances, but there's only so many players that are deemed stars in the MLB, and that's what the Cubs are still missing today. If Ricketts doesn't want to open up his checkbook and acquire a star, then that's on him and not Jed. Regardless, the Cubs are going no where without that type of player in the lineup. Sadly, Busch doesn't move the needle in my eyes.
