Since you didn't answer my question...I know you don't have an answer.
Well that's a hell of a cop out. Here's an answer, if Jones started a game where Zeke Elliott only got 3 touches in the final 3 quarters then he probably loses too. The fact that OSU couldn't do anything on offense in that game and yet Jones still stayed on the bench says more about Jones than it does about Barrett.
That's beside the point though since you didn't even ask a question. You just made an arbitrary statement that had nothing to do with the topic of discussion.
But to answer YOUR question.. Last year under Herman, OSU ran a Pro-Style offense which was suited for Jones' game. This year, no Herman, they tried to fit Jones into what they did last year w/Barrett...although Jones himself didn't change, the 'results' did because he's not a Read Option QB.
You don't seem very familiar with Tom Herman's offense. Pro-Style is the last way I would describe it. The offense was built around Barrett last year, who finished 5th in the Heisman after accumulating 3800 total yards (900 rushing) and 45 TD's (11 rushing) as a freshman. Just watch Herman's team at Houston. The entire offense is predicated off the read option and QB run threat. His QB this year ran for 1100 yards and 21 TD's.
In his 3 starts last year under Herman, Jones averaged 15 carries per game. In his 6 starts this year he averaged just 7 carries per game. The numbers don't add up with your argument.
The results changed because OSU tried to put more on Jones' plate as a passer this year and he couldn't handle it. OSU tried to run a vertical passing game to take advantage of Jones arm strength but teams started playing over the top and he couldn't find his check-downs or throw accurately underneath. OSU eventually had to go to a 2-QB system where they benched Jones once they got to the red zone because he couldn't convert scoring opportunities. This eventually led to Jones getting benched permanently because Barrett was just a much more efficient QB.
Conclusion: He'll be a better pro than collegian and is a better "Pro Ready" QB than Goff, Lynch, Cook
He may very well be a better pro than college player, although that shouldn't be too difficult considering he only threw 15 career TD passes in college.
However, 9 career starts and getting benched your final year hardly screams 'pro ready'. Especially when compared to guys like Goff, Lynch, and Cook who have 36, 37, and 38 career collegiate starts.
