You should try doing your homework first.
Jameis' physical attributes are very close to Big Ben's. He's 6'4", 231; Ben is 6'5", 240. Jameis had a faster 40 time going into the draft while Ben had a slightly higher vertical. Their 20-ss times were basically identical. In college, their per-season average completion percentages were both around 66%, and they both threw for well over 3,000 yards and ~30 TDs (Jameis a little more, Ben a little less) per season. In the pros, they are both elusive pocket passers who love to throw it deep (Jameis was third in air yards per attempt this season behind only Matt Ryan and Kirk Cousins). As for Rivers, it's admittedly a more superficial comparison. Jameis, like Rivers, is a fiery leader who succeeds despite having an unconventional throwing motion.
Who gives a that he's rushing more? I said that he was closer to Big Ben and Rivers than other BQBs, not that he was exactly the same as them in every aspect. He's still a great passer first and foremost. He's the first player in NFL history to throw for 4,000+ yards in each of his first two seasons, he has the second most passing yards by a quarterback in their first two seasons and the fifth most TDs. This is despite only having one receiver (Evans) that scares any opposing defenses. He's not a game-managing scrub with wheels like Struggle Wilson and Dak Prescott, nor is he a glorified fullback or halfback playing quarterback like Scam Newton and Tyrod Taylor.
