Fred Taylor WILL be wearing a gold jacket sometime in the future ... so says the Jaguars legend himself, who tells TMZ Sports he has "no doubt" he'll get in soon.

"We're going to get it," Taylor said leaving Prime 112 in Miami recently. "I believe in the voters."

Fred has a pretty good case ... the former Jacksonville running back ranks 17th on the all-time rushing yards list with 11,695 -- and he did score 66 rushing TDs as well.

But, with his former team not listing him as its greatest-ever franchise player (the Jags famously put Tony Boselli ahead of him last year) ... some wonder if Fred truly will get in.

"Yeah, we'll get it," Fred told us confidently. "No doubt."

As for the current state of the Jags, Taylor had an interesting take on the current QB conundrum in Duval.

The Jags paid Nick Foles a TON of cash to be their starter this past offseason ... but he was outplayed by Gardner Minshew -- and Taylor tells us he thinks Gardner should probably be the guy going forward now.

"I think the locker room might have a little bit more faith and trust in Minshew," Taylor says.

The ex-RB made it clear, though ... don't sleep on Foles by any means in 2020.
