Obviously, you have to do your due diligence with a guy locked in so long at big bucks, but nobody is a sure thing.
Buster seemed pretty sure Rockies would have to pay down a chunk of Arenado’s deal to move him, so there’s that, and might not get back major prospects either.
Whatever Cubs offered to Boras/Bryant awhile back, it must have been a sizable amount to lock down 3B. All bets are off in these times, but one would think Cubs like Arenado's typical overall game.
