I put him in my first pre-season mock for the Chiefs in the fourth round.
He's athletic (which Brooks contridicts, but he's been stated to run about a 4.8 in the 40) and has a big arm.
He's streaky and will try to force throws a lot during a game thinking his arm will bail him out.
I wouldn't spend a first rounder on him as it's going to take some time with an NFL coaching staff to get him to make better decisions with the ball, especially against NFL level defensive backfields. (Which is one of the biggest reasons I like Geno Smith as he's superb with his ball placement, even on the long ones.)
