I'm still pretty high on DR. I think your last couple of sentences there highlight the "he's just 1 of 11" challenge that football inherently brings. It seems most experts/analysts are still very bullish on DR for his capabilities as an 18-year-old with one season of experience and the relative lack of elite talent around him. Freshman errors are compounded when the other guys you're relying on aren't stepping up and DR was always going to need a lot of help this season. He'll get better with time, but he also needs some NFL talent around him at the skill positions.
That's not to say he's been perfect, but if you look at most of the remaining CFP teams this year and their offenses, what do they have? Veteran QB with roughly 30+ starts under their belts (Will Howard, Dillon Gabriel, Quinn Ewers), NFL wide receiving talent (Egbuka, Jeremiah Smith, Isaiah Bond), and elite O-lines. DR has none of that, and the lack of those resources lead to situations where he finds himself trying to rush for a first down and doing something a bit bone-headed like sliding early.
