Guess I'll be in the minority here, but I think Murray is arguably the best QB prospect of the last several years. Mayfield probably is a little better passer, and that may be preferable for some offenses/coaches, but Murray is a great passer, with almost unrivaled mobility, that every defense will have trouble accounting for.
Forgive some hyperbole/strong optimism, but I think Murray has the potential to be a much better QB than Russell Wilson, or at least what Seattle asks of him. There is a Steve Young level ceiling here. Murray is the player people wanted Michael Vick to be that he never really was other than maybe a half season with the Eagles.
So he's small, so what? The NFL is changing, actually it already changed, teams and coaches are just slowly catching up. You can't grab small speed WR's, you can't blast QB's who dare to leave the pocket. Aggressive QB's are usually rewarded, either with big plays, or drawing penalties attempting them, and Murray is plenty aggressive. I'm not concerned about Murray's size, so he'll have a few throws that will be more difficult for him than they would be for say, Ben Roethlisberger, due to his height, again, so what? He brings things to the table that nobody else in the NFL brings.
Murray is very accurate, more so than any other QB in this draft, and has exceptional pocket presence. He'd be a top QB prospect even he ran a 4.8. He's not looking to run if the 1st read isn't there, and often takes off, to find a better passing platform, something we saw Mahomes do plenty of times in 2018. He runs when he sees a lane, and is able to outrun guys who have angles on him, like a punt returner. I'm not worried about size hindering his durability either, he's not skinny, he's got a higher BMI than many starting QB's. If Murray were to be a RB, he'd likely be the top prospect at that position too.
I'm extremely excited to see Murray in the pros, whether he ends up with Kingsbury or not. Part of me wants to see him end up in Oakland, with Gruden and Antonio Brown, and watch the track meets that he and Mahomes will produce twice a year.
From a fantasy perspective, I'd have no problem taking him in round 1 of dynasty drafts, maybe even in the top half of the round. He's a rare QB who could be a weekly difference maker.
