He certainly can, but I wouldn't bet on it. In general, lack of experience is a knock, because a QB is more likely to regress after a great season than he is to improve. How much and why he regresses is part of the evaluation. Murray and Haskins won't have that to evaluate, so it creates some doubt. I'm less concerned with Murray, because he reached a higher level of excellence and because he has a more dynamic skillset. Haskins has fewer ways to succeed. Haskins has less margin for error. Put him on a good team and give him a year, and I like his chances. Put him on a bad team, and I don't know how many plays he'll create. I think some level of early success is important, and I'd hate to see him Josh Rosened. I still think Rosen was a pretty good - if overrated - prospect, but his chances really took a hit with that dumpster fire in 2018. It wasn't all his fault, but he was so bad that you have to seriously question whether he's already broken. People will point to Goff, but it was much worse than Goff's rookie year, and it was bad enough to make Rosen and outlier if he turns it around.
I like Haskins slightly better than I did Rosen, but I think they're dependent in similar ways.
