IRVING, Texas (AP) _ These should be high times for Dallas Cowboys quarterback Drew Bledsoe. It's six weeks into the season and Bledsoe has guided the Cowboys to a 4-and-2 record and first place in their division. He's the top-rated passer in the N-F-C and recipient of the label "best Dallas quarterback since Troy Aikman." But the good news changed this week after the Cowboys learned that Bledsoe's most vital blocker is out for the season. His most sure-handed receiver is lost for at least one month. The Cowboys on Sunday will visit Seattle. If Bledsoe does anything wrong, there could be questions about whether he messed up because he was concerned about a blind-side hit now that Torrin Tucker is manning left tackle -- instead of Flozell Adams. Imagine the uproar if Bledsoe makes a mistake on a pass to Peerless Price, the obvious replacement for Patrick Crayton and someone the quarterback lobbied the club to sign. And -- what if running back Julius Jones misses another game because of his sprained ankle?
