Haskins looked like shit, his stats look nice and the story will be that he led them back to the win a hostile environment, which he did, but he couldn't complete much of anything except screens that took advantage of PSU's aggressiveness. He could definitely improve as the season goes on, and I might take the chance on him anyway because he definitely has the tools, but he'd probably be better served staying another year.
If Grier keeps playing like this when the competition improves I'd take him top 10 for sure. He looks like a poor man's Baker Mayfield, not quite as mobile, not quite as strong of an arm, pocket presence isn't quite as good, but he's extremely accurate and has pretty good mobility/arm strength/pocket presence.
