You are using too much reasoning. The push from teams has been commit early or you will lose your spot. Will they stop recruiting top players at that position? Likely not (unless they got their top options already). Will they tell kids that? absolutely not.
Also the last sentence threw me off.... the first sentence seems to say if they land top national guys UGA will push Brinson out, then you say it makes sense for small guys to lock up spots but not top guys (assuming you meant Brinson?) So Brinson is a top guy for UM but not UGA? Also idk if UGA would take Brinson, a top 150 guy from a So.Fla. school that produces top talent every year, and then push him out. IDK if I have ever heard of that happening before.
