If I’m GM, I tag Fowler and try to trade him. I re-sign Littleton, and try hard to re-sign Brockers — a seriously underrated and valuable Ram.
But I’m guessing they won’t do the above, and likely can’t keep all three. It might actually be impossible under the cap, without a major “home team discount,” especially from Brockers. That sort of thing is pretty rare these days.
Likely reality: They re-sign Littleton and the other FAs walk, despite best efforts from the Rams.
