We know all interceptions aren't created equal. And it was clear this season, if you watched Winston consistently, that he wasn't always in sync with his wide receivers; he lost Kelvin Benjamin and Kenny Shaw to the NFL, two of his favorite targets. But a number of his 18 INTs this season were forced throws and simply inaccurate, and I think he actually regressed in terms of his willingness to check it down and not always look for the bigger play. He'll need to continue to improve his ball placement, because it's simply not elite. And he needs to be better about forcing the ball into tight windows.
That said, I do think Winston makes mistakes of aggression because he can make pretty much every throw, and he always sees opportunities. And don't let someone tell you the INTs are a nonstarter. After all, Matt Ryan threw 19 of them in his final season at Boston College before going No. 3 overall in 2008.
