Impact is more important than stats, but how exactly that is defined is subjective.
Bledsoe was not just a volume stat QB, his efficiency compares favorably to HOFers such as Elway and Marino.
Another critic claimed Bledsoe wasn't ranked among the best when compared to his contemporaries. The reality is Drew has ranked among the top-5 in completions four times (1994-#1, 1996-#1, 1997-#2, 2002-#3), in yards five times (1994-#1, 1996-#3, 1997-#4, 2002-#2, 2005-#4) and in passing TDs four times (1994-#4, 1996-#3, 1997-#3, 2005-#4t). In fact, just last season ('05) Drew was #8 in pass attempts, yet still ranked #4 in passing yards and TDs.
Some critics want to point to his W/L record. As some have already pointed out, winning isn't the result of a single player's impact. Still, Drew has a winning career record. Now let's put that in context. Drew was thrown to the wolves as a rookie on a team that finished 2-14 before he arrived. He led that team to a Super Bowl. Drew was then traded to a 3-13 Buffalo team and played his way onto his 4th Pro Bowl in just his first year there. Now he's playing for a Dallas team that went 6-10 before his arrival. Anyone taking wagers he won't finish this season with a winning record?
Based on Drew's performance through the first five games (NFC Offensive Player of the Week, two time FedEx Air and Ground award winner, #3 passer rating, #3 passing TDs, #4 yards, etc.), it's rather apparent what Drew's capable of when surrounded by a half-way decent supporting cast, IMHO.
