At 40 million AAV, the Dodgers, Phillies, Mets, Yankees, Giants, Cubs, and Blue Jays are all in the market
I think the term scares away more teams than the AAV. Best guess is he is good until about 32, so a 15 year contract is going to have like 8+ dead years on it.
I don't know who a comparable is for aging, but I looked at some of the great Dominican hitters. Vlad and Pujols didn't do much past 32. The PED guys played well for a lot longer (Manny,Ortiz, and Sosa). In retrospect, it sure seems that PED definitely helped a lot of hitters hit well into their late 30s.
For other comparables, Trout may not have a good season over 30 yo. Bryce seems to have started his descent around 30-31, and it remains to be seen if that continues, or he has a bit of a bounce back, or at least stays about the same.
He's more valuable to the Yankees right now than anyone else. They should just come up with a deal before he hits free agency. I know Boras won't do that though.
