Yeah, but what you're forgetting is, Seattle's and Francisco's offense is predicated off of their running, NOT THEIR PASSING GAMES.
So most of the success that those guy will have, is because of the threat of their running games.
Take Marshall Lynch and Frank Gore off those teams, then see how well those guys will throw when it's a staple of their offense?
Remember, despite what you said. Both Seattle and San Fran ran the ball much more than they threw. They're running teams, not passing ones.
And it is/was clear, that both Kaepernick and Wilson were spoon fed along their first NFL seasons, by heavily relying on their running games, and utilizing many quick throws to offset their lack of reading defenses and responding to pass rushes.
Not saying Wilson hasn't progressed and gotten better. He has. However, they're are many things which he doesn't have to carry the burden with in Seattle. Kaepernick's even worse. At least Wilson can scramble and buy time, then hit a receiver (albeit with a circus catch). RG3 and Kaepernick, usually bolts in that type situation.
Yes, Luck is over rated indeed. However, it's usually the case, 'the more you throw, the worse your percentages are (especially if you're losing big)'. As I stated, it doesn't happen with Kaep and Wilson as much, cause they have cushy run games, offensive lines and defenses to rely on. And how often, were those guys ever behind big in games?
It doesn't matter what their offense are predicated off of. The fact of the matter is both Wilson and Kaepernick...when asked or required to throw the ball more--whether by game plan or in-game circumstances...generally arises to the occasion.
One could argue that their better days are days in which the running attack is LESS featured in their respective offenses.
And Minnesota's offense is predicated off of the running game. It doesn't stop their passing attack, when needed or required or desired, from being mediocre at best.
Young Brady benefited from a solid running attack...didn't stop young Brady from lighting you up when needed or required or desired.
The same argument I had on another board. Everyone predicated that if you took Mike Vick and threw him into an offense (Like Andy Reid's) that Vick would NEVER succeed. Then Vick's second year in Philly happened.
You CANNOT make predictions on what QBs will do (especially young ones) in differing offenses. The BEST we can say is that Wilson and Kaepernick are generally efficient within the confines, boundaries, and limitations of their team's offensive system.
For all we know, you put Wilson in Denver's offense and he throws up 7000 yards and 80 tds.
