Re-read my comment #12 (how appropriate). Just because he doesn't attach his name to everything he does, ala Ted Turner or Robert "KKK" Byrd doesn't mean he isn't giving back.
There are many worthy charities out there who get lots of support from athletes quietly. I never heard of a "Ted Williams Foundation" or a "Tim Wakefield Foundation", but there's this little group up in Boston called "the Jimmy Fund" that owes much of its continued success to the various sports teams (and their stars) up there.
The point is that the Globe checked and high-lighted metro-boy as a slacker. They did the research, printed what they found and it went unchallenged. You saying that lots of guys give without fanfare may be so but the research shows that your hero isn't one of them.
