David Carr Signs with the 49ers

[Senser81]

There are a few QB's in the league with bad mechanics, and it hasn't hurt their legacy.

Phillip Rivers - Winner/Best QB rating in NFL since 04
Vince Young - RoY/Pro-Bowler/Great Winning %
Donovan McNabb - No explanation needed


Plus there are more.

This is what bothers me about the Tim Tebow discussions.

Phillip Rivers was incredibly accurate in college. He was compared to Bernie Kosar in terms of side-arm delivery, but Kosar was a damn good NFL QB, too.

McNabb was great in college, but I wouldn't put him on the same level as Rivers when it comes to accuracy. This kind of shows up in the NFL, too, where McNabb will have long stretches of one-hopping passes to WRs.

Vince Young had a nice last season in college, but he's nowhere near Rivers or even McNabb in terms of accuracy. He's actually probably closer to Tebow (albeit better).

the biggest problem with Tebows mechanics is that it takes him 3 days to go through the whole motion...the only QB I can think of with a similar motion is Lord Byron and look how his NFL career has turned out, despite being a more polished passer than Tebow. Having a windup longer than that of many MLB pitchers is a much more blaring mechanical issue than throwing at a slightly different angle and having your release point being a little off. Combine that with his lack of experience taking snaps from center, and that is the vast ajority of the mechanical issues with Tebow. They are completely different than the issues someone like Rivers has. Rivers cam from a much more pro style offense, is a more accurate passer, and is a much more traditional pocket passer than Tebow. Its two completely different situations with the only similarity being that they both happen to have atypical motions that are completely different from each others. One motion is slightly off (Rivers) the other is a potentially huge problem (Tebow), especially with the speed of NFL defenses and the timing required by many NFL offenses.
