Well, now that he is retired from baseball I wonder if that will have any implications for MMP? Perhaps he will take a more active role in the company's management.
I seem to recall that he said once that he promised his wife that MMP would be a self-sustaining business, in other words his baseball earnings were not going to subsidize his hobby. So I wouldn't expect his retirement to mean more funds for the business.
On the other hand, he may have more time available, even if he spends a lot of it on other business opportunities. That time may very well have a lot of value in itself, but it also could mean a better focus. Given that Schilling is obviously a highly competitive person, directing some of his competitive energy into making MMP a bigger company wouldn't be surprising.
