The first was that Jameis Winston would lead the NFL in passer rating and touchdowns -- in preseason. That's fairly unlikely, given the fact that well over 100 quarterbacks will be throwing passes during the preseason, and Winston shouldn't get a particularly large amount of playing time. It's also not particularly relevant, because who cares about preseason?
The second prediction is a lot more interesting, though. Here's Mike DiRocco making it:
34. Tony Romo will get hurt (again), giving Bucs QB Mike Glennon a lot of trade value. A desperate Jerry Jones will make Tampa GM Jason Licht an offer can't refuse for the fourth-year QB. -- Mike DiRocco
That's quite a prediction. The Bucs had talks with teams about trading Glennon before the draft, but those talks didn't go anywhere. Every team that could have been interested in Glennon used a draft pick on a quarterback, and apparently none of them were willing to give up the kind of pick the Bucs wanted for him. Glennon is just a one-year insurance policy for the Bucs at this point, though, and the farther they get into the season with Winston still healthy, the more attractive a trade will look. The alternative, after all, is allowing him to walk away in free agency.
There are a few reasons why this is highly unlikely, though. As noted above, every team that needed a quarterback, added one in the draft. They're a lot more likely to just play those backups than to trade for Glennon in case of emergency. More than that, trading for a quarterback in midseason is a terrible idea, because there's no time for the quarterback to get acclimated to and learn a new offense. That leads to hilariously terrible performances, as we saw when the Vikings picked up Josh Freeman in 2013 and the Raiders traded for Carson Palmer in 2011. A team would have to be truly desperate to trade for a quarterback in the middle of the season.
While it would be nice for the Bucs to get something in return for Glennon, that ship has almost certainly sailed.
