I really like Dylan and he has shown so much potential and has played really well at a high level for a true freshmen QB.
So the things that he could do better, I will give him a pass as a first year player.
Having said that

..... Bruh, those short passes need to be out of your hand quicker. And more accurately. You got open guys in the flat a lot in every game (Fidone, Lloyd, or RJ & EJ).... but by the time you decide to throw it to them, they are almost covered and the passes are floaters.
Need to read the space quicker (the field and coverage). When they are open, zip it to them and allow them to catch and run. Instead of a 5-10 yard play happening, it's 1-3 yards at most.
Also need to step into throws more often.
And it seems like every other pass to Fidone is around his ankles or slightly behind him. He doesn't have the knees for that. Get some better accuracy and put some mustard on those throws.
And don't take a sack when there is a skill player standing alone in the flat looking at you as a safety valve. We all know he is open. A 3 yard pass play is better than back peddling in the pocket and getting sacked or throwing it away.
Plus, if you escape the pocket by running around, that's when refs throw flags for holding.
So yeah, a bit more accuracy, embrace positive yards, step into some throws, and put a little less air on the deep ball.
Other than those few criticisms, DR is one heckuva player, so glad he is here, and the sky is the limit when it comes to how great he will become.
