Collins is not a guy who's good enough to headline a deal for Hader. So far major league pitching has overpowered him to the tune of 44 K's in 102 AB's. It's also questionable if he can remain primarily a catcher. Besides the White Sox gave lefty reliever Aaron Bummer a hefty contract a year ago. Bummer is their closer in waiting. Collins could be had for a lot less than Hader. He's got no position on the White Sox and he's already used up a couple options. Collins 44Ks in 102 ABs, Hiura 192 in 594 ABs. By that metric, I guess major league pitchers have been overpowering Hiura too? I have no idea if Collins and other pieces are a fair return for Hader, but a young major league ready talent with the pedigree and minor league numbers to suggest he will be an impact player at the major league level at a position of need for Milwaukee. There isn't a contending team in either league that would not have some degree of interest in Hader, he's the most dominant left handed relief pitcher in the game with multiple seasons of team control. I can tell you, the Brewers are on pretty equal footing in their division, and their nucleus is ready to win now. They are not going to ease off in 2021, trading Hader for minor leaguers that are a year or more away from the major leagues. Any trade involving Josh Hader is more probably true than not, going to bring back talent that immediately plugs into the major league roster. Hiura's actually had success in the major leagues. Collins hasn't been on any top 100 prospect list since after the 2016 season. That's four years ago. I wouldn't be opposed to the Brewers targeting him in a deal, but certainly not as a headliner for Hader. I have friends who are Sox fans. They'd be giddy if the Brewers did that. At best he'd have to be a secondary piece for me to be interested. But Sox gave Aaron Bummer a 5 year deal. They like him a lot. I don't see them as Hader suitors. I'm not advocating Brewers trade Hader for minor leaguers, but Collins isn't a bona fide major league bat either and one position Brewers have talent at in their system is catcher.
