Of course the assumption behind those incentives is that A-Rod is some kind of beloved figure to the fans. They feel the same way about him as they do towards Rivera and Jeter and they'll come out to see him pile up the numbers.
I might add that A-Rod isn't being paid for RBIs. His package, which everyone agrees was mistakenly over-generous, is based in large part on the revenue he can generate as he cruises past milestone after milestone. As we saw over the weekend, he's going to continue to do that, even if he's not the player he was.
I think that's wrong.
