Winton's accuracy can improve as a whole as he has a tendency to miss throws a la Eli Manning at times. That said, his play isn't without promise. Both of you, in addition to everyone else, have to remember that Jameis is only in his 2nd year. Yet still his numbers already reach historic and heroic proportions. In 2016 Jameis threw for the 3rd most Air Yards Per Attempt--higher than virtually every 2nd year QB that ever played a full 16 game season--at a 60% completion rate clip. To put these numbers into perspective, only Russell Wilson's 2nd year numbers approach Jameis' efficiency through the air. So Winston is in league with a Superbowl winner as far as his deep efficiency goes already.
That being said, while Mike Evans is a monster in the deeper waters of the field, defensive coordinators knww Jameis' tendency to throw to Evans all last season and so attempted in 2016 to shut that aspect of the field down. I wager that Jameis deep accuracy floundered more because of a lack of weapons and coordinator adjustments, rather than Jameis' lack of ability downfield. Outside of Evans, Winston's receivers were UDFA material in his 2nd year: Mike Evans, (good starter) Cecil Shorts (UDFA), Vincent Jackson (too old and can't seperate), Adam Humphries (UDFA). This is a better receiving core than what the Jets kindly gifted Geno Smith in his 2nd year before kicking him out on his ass, but not good enough for a mechanically-improving-but-still-developing QB like Jameis to compete.
After the draft now Tampa Bay's GM finally sees the light. He signed Desean Jackson to spread the field and draw coverage, Chris Godwin to do the same, with Jameis reaping the benefits as a deep ball maverick. So alongside Jameis' natural improvement as a third year passer, there should be an improvement all around from him, including his deep ball.
