Based on nothing?....more like based on what you hear about a guy's skillset. You can disagree or whatever, but it's not based on nothing.
For example:
Cody Green, 4 star QB and all. Read about his recruiting and you would know his raw background in passing. For some reason, nobody expected him to be a raw thrower even in his first year.
Taylor Martinez, elite big play explosion, completely raw in a lot of QB aspects as well as passing/mechanics. He's come a ways, certainly, but again people do not realize this for some reason and keep calling for an injured Taylor to pass on the run on rollouts, when his mechanics even when healthy and sitting back in the pocket are as formative in development as they are.
Brion came here touted as the 2nd best passer on the team already, can make some big time throws and brings a lot of running threat with him, though he may not be as
fast as Taylor. It's just why people are excited about him and why he *could* give Taylor a run for the money. Taylor has a year under his belt and obviously the leg up in terms of time, but it isn't an advantage of several years and Brion has the leg up, or rather arm up, in passing. Of course who knows how that will all transpire on the field - I am just saying it should be a good competition.
I dont get either why everybody is so high on Carnes who hasnt even taken a snap in practice with this offense(Im assuming).
????? Odd assumption. (Granted, unless you mean with the 1st team. Don't think he has done that, not sure) Hard to give our defense fits in practice if he doesn't even take practice snaps.
Kinda pointless to try to ignore reports about what a player's strengths and weaknesses are IMO.
