Some real honesty from Jameis Winston -- who says he had to check his ego to become the backup QB for the New Orleans Saints ... but thinks it's worth the investment.
Winston -- the #1 overall pick in 2015 with the Bucs -- just signed a 1 year deal to back up Drew Brees in N.O. ... and calls it a "once in a lifetime opportunity" to learn from one of the best of all time.
"It was no better position than to be in the same room with someone that I’ve really looked up to, someone that I admired since I’ve been playing this game in Drew Brees," Winston said on "Chalk Talk" with Charlie Ward.
