He's a classic pocket passer playing in a Dan Mullen spread offense that utilizes a bunch of NFL level concepts but is usually reliant upon super mobile passers(Alex Smith/Tim Tebow/Dak Prescott). He's got very good size for the position, coming in around 6'4" and 240, patient in the pocket with a quick release to get the ball out in a hurry and has shown the ability to diagnose defenses, manipulate defenders with his eyes and just enough mobility to be a threat to take off, especially down near the goalline, utilizing his size to full effect. He's reasonably accurate but could stand to improve his footwork to get better ball placement but he's great at getting his playmakers the ball in space to pick up YAC.
I think everyone is intrigued by the crazy potential of someone like Trey Lance but I could see Shanahan going through the film of a guy like Trask and being smitten. Trask is by no means a finished or fully developed product. He was backup all throughout high school, a backup to start college and a guy who was basically doing the work and getting ready to step in and play and when he got his opportunity, he made the most of it. He has a lot of room for improvement with his footwork and stepping into throws, has a tendency to throw high at times but he's already looking quite improved this season from last year.
