it depends on their work ethic.
cam's mistakes aren't like all those other guys...esp. guys like ryan leaf, VY, jamarcus russel, and david carr.
lumping all these QBs in together is quite frankly weak, but whatever. you've got a point to make and you're going to be grasping at whatever straws you can find.
many of those guys did have competition, though. VY had collins, leinart had warner, grossman had orton, harrington had garthia, quinn had DA. competition didn't help any of those guys. they just sucked.
ryan leaf was just bad. he was known for having a poor work ethic, just like russel. neither one of those guys had much of anything to offer other than being a big guy with a cannon for an arm....mainly the cannon...and were overrated because of that. they came with very little in the way of a history of working hard or had much to offer in terms of mechanics. teams foolishly thought that the rest could be coached up, even though they had no history of doing that or being receptive to that. leaf was a headcase who cursed out everyone and attacked reporters. russell was more interested in showing off his money than he was earning it. cam has nowhere near the issues that those two had.
david carr and VY were both shell-shocked players for different reasons. carr couldn't handle the pressure on the field and VY couldn't handle the pressure off the field. neither have shown the fighting spirit or the mental toughness that cam has shown. granted, cam needs to grow more there, but both of those guys gave up in one way or another...esp. VY. i doubt either guy would have ever been able to handle the pressure of the game full time which is why you see them on the bench, if they're lucky. cam may have pouted, but he's nowhere near the mess that either one of those two guys are.
harrington was overrated, but still was the victim of being on a very bad team with some of the worst management the league has ever seen (worse than the mess we have here, believe it or not).
quinn was just flat overrated because of where he went to school and who his coach was.
kerry collins problems were that he was a pathetic racist drunk who quit on his team and who never liked it here because of the color of the uniform.
you are reaching for reasons to hate on newton, but keep on, though. it's always funny to see what lengths people's narrow/closedmindedness will go to in trying to drag that guy down into the hole that fellow closed-minded people tried to paint him into before he was drafted.
Im not reaching dude. I was happy we drafted him. BTW when they brought in Warner to compete with Leinart what did the Cardinals do........went to the Superbowl.....thx for proving point. I don't hate Newt.....just wish he wasn't such a dumbfug with the football.
