The only garbage time stats Jameis has based on standard garbage time metrics (4th quarter down 2+ TDS) was during the Bucs game. Also, if it is such a small sample size, how do we use that to determine performance, especially when Derek Carr's numbers wasn't that far off. Makes you wonder.
You're only using stats to "determine performance." NFL professionals use tape to determine a players actual performance. That's why NFL professional don't have the same performance evaluations of Carr and Winston that you do.
QB stats tell you what happened, but they never tell you why they happened or who performed well or bad. There's not a single QB stat that is the sole result of the QB's performance, so it's impossible to truly evaluate a QB's performance without watching their play on tape.
And the NFL professionals analyze every play of a player, they don't base their evaluations on just 1 or 2 games, or some highlight reels. They study the All 22 version of every play.
