So I think my hugely optimistic scenario, assuming the Cubs are willing to go above the cap, but not crazily so would be something like this. It does not include unrealistic things like Bellinger/Tucker/Bichette and does not include Framber or Ranger because frankly it seems like the Cubs have no interest in them barring their market full on imploding
1) Grab Zac Gallen at like 3/70 to 4/85 and follow that up with trading Taillon, hopefully for a SP prospect because god knows the farm needs it. This gives the Cubs a long term piece for the rotation and removes one of a half dozen or so guys that will need to be replaced at the end of 2026. There's a bit of upside there beyond Taillon, but mostly it's just trying to make Jed's life not a nightmare after this season.
2) Grab Seranthony Dominguez on something like 2/14 to round out the pen, the stuff is good, the control is not, see if a better pitch lab can get him squared away
3) I'm torn on this because frankly I like non April Alcantara and he provides so much more upside, but if they wanted to play it safe, you could pick up Tauchmann. He's a good 4th OFer, he's not exciting but he's safe and that's pretty much his selling point.
They'd be incredibly deep in the pen, rotation and with the bats which they need to be if they're not going to have a mega star to carry them.
