For our money, baseballs’ biggest problem ain’t steroids, it’s the lack of a salary cap. (Have you seen the KC Royals’ roster? It looks like something from an unlicensed Super Nintendo game.) That said, next week’s House Government Reform Committee hearing (Thurs) promises to make gripping TV (gosh, C-SPAN could make a windfall putting it on PPV). Will Giambi crack? WillCanseco shill his lousy book? Predictably, ESPN promises the most intensive coverage, sending Mark Schwarz (and possibly Roger Cossack) down to DC and kicking it back to Bob Ley in Bristol for analysis and wrap-ups. Comcast Sports Net DC/Baltimore will have reporters on the scene, with coverage carried by the MSO’s Philly and Chicago RSNs. One holdout is Fox Sports, which won’t be covering, as it no longer has a national news show.
