Dak Prescott's throwing mechanic is, in a word... poor. Looks like he stops entirely and raises up on his tippy toes to throw (reason he appears to throw off his back foot). Seems telegraphable; easy picks. Gotta look like you can still move when throwing...
Elliott just appears to be in a whole other league of 'natural' movement than the rest of the backfield goons.
Receiver group still looks overly pedestrian. Can we bioengineer a serviceable wideout using Ed Eagans drive/ability, mated with Rico Gathers' size (holy crap that guy is a GIANT..but didn't look too coordinated).
