Flat, there might probably be a couple, few, some, who are doing as you are thinking they are doing.
1. Cooper was, is, probably every bit as good as you, the facts, info, recruit rankings, offers, etc, say.
The thing is tho, that in thursday night football, in spring ball, and in Fall Camp, Leach, the coaches, leaked out that Cooper was not ready yet, not as good as Minshew, Tinsley, Gordon.
And based on everything, it looks like so far, unless Cooper tears it up in spring ball, fall camp, Thursday Night Football, etc, that he Cooper will, would probably not start next season, and probably be 3rd on the depth chart behind either Tinsley, Gordon at #2, if Gubrud comes, #1, an #2, if doesnt come.
So because of that folks have pretty much written Cooper off for next season until the year after next season that he Cooper probably start if he is not beat out by Cruz.
As to Cruz, while he may not have had the offers, the recruit ranking, Cruz seems to have just as good tools as Cooper, and maybe even 1 tool better. Cruz has better looking film then Cooper. And Cruz has won a lot of awards, done well in QB camps, 7 on 7's, evaluations, competitions, etc, to the point that many were shocked when he Cruz was not upgraded to a 4th star, and only had 1 recruit service outside of ESPN, Brand X, Rivals, 247, that may have been like Bleacher Report that gave him Cruz a 4th star. Cruz is looking good in his spring practices. And he Cruz might or might not, may or may not do good in spring ball, fall camp, and Thursday night football. We will see what happens. But as good as Cruz is or may be, he is still at least technically only ahead of Neville, Bledsoe, in 4th place at best, 5th place at worst depending on if Gubrud comes or not.
Cruz is just like when somebody gets a shiny new toy. Almost everybody likes the Shiny. Does that mean that the Shiny, or Cruz better right now? No.
Leach has PROBABLY EITHER said OR thinks that Gubrud will PROBABLY(Doesnt mean he will be(probably about 85% chance he will be starter) be the starter if he Gubrud comes.
And if doesnt come, Tinsley probably be starter(probably about 73% chance)
And if not Tinsley, then Gordon(Probably about 35 to 43% chance to start)
And if not that, then Cooper(Probably about 18% chance to start)
And if not that, then Cruz(probably about a 4 to 7% chance to start.
Bledsoe: 1/2 of 1% chance to start.
Neville wont stsrt. 0% chance, will transfer.
