If we have Cleveland in a corner, we should be trading our surplus infielders for him. Hiraldo + Lopez + Jimenez, not our current OF.
My take on the regression issue:
If LG Jr has a poor start to the year, I would be holding out hope it's just a slump, and that he will recover for the remaining MULTIPLE years of control. He's one of the only guys in our system that looks like a competent OF - he does have ~ 1 yr of high level production.
At the trade deadline, I won't be wishing I had traded him for Lindor anymore than I would Vlad or Bichette or Biggio (presuming we could also get Lindor for the afformentioned three). I'd probably be worried about the fastly approaching FA period, and losing Lindor for a 2nd Rd draft pick.
Lindor just had an entire 60 game season of offensive regression, are you worried, or do you expect him to bounce back?
