I never said Lewis was slightly better than BJax. He is substantially better. His shortcomings (long wind up, slow decision making) can be corrected. If Shrout is better so be it.
Lewis was not statistically different than Dylan Morris at UW, Ethan Garber at UCLA or Will Plummer at AZ. All of them were within 24 pts. of one another in QB rating, and .8 ypa of each other with Lewis having the second best QB rating of the four. Garbers did not play a great deal, but the point is Lewis was on par with the other 4 frosh P12 QB's and simply doesn't deserve the narrative that he was comparable to BJax. He put up numbers that compared, on the average, to any other P12 frosh QB, and he did it with probably the worst OL in the conference in front of him.
Now, perhaps Shrout is better. Perhaps Lewis will not show the improvement one expects. Normally most players show the most improvement in their second year starting. But I think it is BS to create the narrative he is some sort of crappy QB and the cause of CU's impotent offense last year. He was one of the few bright spots, and given his well-documented areas that need improvement, that is saying something.
Lewis had a 3 to 1 TD to INT ratio. His ypa of 6.0 was below par, but no different that the other frosh QB's noted above. He did not produce a lot of offense in pure numbers, but he also had the fewest attempts of any P12 QB that played regularly, aside from Garbers, who was DTR's understudy. I completely disagree with the "Lewis is slightly less ****ty than BJax" take.
