Normally, Donovan McNabb is a sports junkie, at times something of a news junkie, which means the TV is usually on. But this week, if he was going to keep not only his equilibrium, but also his very sanity, he was going to have to set a rule: No TV, at least no sports or news. There was nowhere he could turn without seeing Rush Limbaugh's comments replayed, without seeing a debate over whether he is overrated, without seeing a panel of experts being interviewed via satellite.
