I will also go on record and say that I hope Newton has the work ethic to set the league on fire. I think that QB's with the skill set of he, Vick and Tebow and the style they play add great spice to the league.
Those guys you listed are great playmakers (or were in college), but let me defer you to a Hall of Fame QB on the difference between a playmaker and a championship caliber QB.
Steve Young's part starts around 1:00 in the video. On a side note: I'm still scratching my head why Rush (even though he's a idiot) was fired or crucified for those comments. I don't think they were that out of line. Hell, Jalen Rose's comments were 10 times worse.
