Well, this will be interesting. Watched 3 cutups of Hooker, and the guy he reminds me of is a rawer Dak. Like rookie Dak.
He's got a snappy arm that's good not great, he can run a bit but doesn't like to, accuracy wobbles, and he needs to see receivers break open before he throws. Cnu is right, he never moves beyond half-field reads.
We complain about Dak a lot, but he's grown up a lot as a player. In his first 3 years, he used to struggle with some really basic stuff, like staring down first reads and air-mailing 3 or 4 balls a game. Hooker is like a throwback to that... a physically capable gamer who doesn't have a grasp on everything yet. Dak unquestionably worked hard and maximized his skillset... there is no guarantee that Hooker develops the same way.
More importantly, I don't see Hooker as a transformational quarterback. The best guys in the league can all "see" space almost instinctively and anticipate it. When Pat Mahomes throws a no-looker or a one handed pop pass, he's not doing it willy nilly... he knows where his receiver and the defenders are going to be a second before they get there. I remember seeing a post game interview with Joe Burrow, when he threw a touchdown to Tee Higgins in bracket coverage. He mentioned that the safety on the play had his back turned, and Burrow saw that he couldn't play the ball before it got there, so he knew that the double team was actually a 1 on 1. And he can process that in under 2 seconds.
Dak's not a guy that can do that. That's why he struggles against zone... he can whiteboard out how a smash concept beats Cover 3, but when the bullets go live, he's not comfortable anticipating that flag-route throw over the flat defender. So he holds on to the ball, or checks it down to Schultz, or forces a tight window throw in there, and generally does the Dak stuff we see every week.
Ultimately, Hooker's not a guy who can anticipate either. He is very much a see-it-throw-it guy and doesn't look quick to process. Combine that with tools that are middle of the road by pro QB standards, and I don't see a franchise quarterback. Dak is Hooker's ceiling if he maximizes himself, and the floor is clipboard holding.
QBs on a rookie contract are such a boon, that I would still take him early second if I was a bad team and missed out on the QBs in round 1. Hell, I could even justify a late 1st because of the 5th year option. Daniel Jones is a bottom half QB in the league IMO, and is asking for 40 million dollars a year. Hooker will never be a top 10 QB, but if he develops to even a Jones level, he will repay your draft pick easily.
