Heading into the 2019 season, everyone knows about the players the Tennessee Vols will be counting on this fall.

Quarterback Jarrett Guarantano, running back Ty Chandler and defensive backs Bryce Thompson and Alontae Taylor are essentially household names in East Tennessee.

But if the Vols are going to reach a bowl game in Jeremy Pruitt's second season, they'll need production from more than just their expected "top players".

Tennessee will need some role players to step up in a big way. In fact, they'll need some of those roles players to become stars.

Fortunately for the Vols, I think there are several players on UT's roster who fit the bill. Players who maybe have become a bit of an afterthought in the shadows of guys like Jauan Jennings.

Here are five "under-the-radar" players that I think will be key to Tennessee's success in 2019.

5 under the radar players who will be key to the Vols' success in 2019 —>>>

Jahmir Johnson — Offensive Lineman

Tennessee's offensive line received a big boost during the 2019 signing period with the additions of Wanya Morris and Darnell Wright.

A lot of folks think the highly touted duo will start from day one on Rocky Top.

While that's definitely a possibility (especially for Morris, who is an early enrollee), it's far from a certainty.

That's because redshirt junior Jahmir Johnson, who made 11 starts at left guard for the Vols last season, could end up slotting in at one of the tackle positions.

Johnson has experience and he's performed well so far during spring practice.

The assumption is that Johnson will absolutely be starting this fall. Most seem to think he will once again start at left guard, but it's very possible he could start at left tackle.

Either way, Johnson is going to be a huge part of the Vols' offensive line rotation and one of the keys to their success.

Josh Palmer — Wide Receiver

Marquez Callaway and Jauan Jennings are the stars of the show at wide receiver for the Vols.

But Josh Palmer is the Vol I think fans are most likely to see streaking down the sideline for a touchdown this fall.

Palmer, who was second on the team in receiving yards last season with 484 (Callaway led the team with 592 yards), is the most dangerous big play threat on the team.

The junior wide receiver averaged 21 yards per catch last season. The next closest player on the team to that average was Callaway at 16 yards per catch.

Palmer's vertical ability should play well in Jim Chaney's new look offense. Chaney is an expert at getting the ball into the hands of his playmakers — especially at wide receiver.

I wouldn't be shocked if Palmer quietly leads the Volunteers in receiving in 2019.

Latrell Bumphus — Defensive Line

If the Vols are going to exceed expectations in 2019, they're going to need a couple of guys to essentially "come out of nowhere" to be contributors.

I think Bumphus is the perfect candidate.

The junior from Savannah, TN is a former four-star defensive end who started his college career as a tight end.

Bumphus has moved to the defensive line this spring, where he's reportedly performed well.

The Vols lost a ton of talent along their defensive line, which means there should plenty of competition and playing time. Bumphus is a great athlete with above average strength. This might be a situation where he switches to the defensive side of the ball and becomes a force to be reckoned with.

Will Ignont — Linebacker

When it comes to linebackers, a lot of the attention will be centered on newcomers Quavaris Crouch and Henry To'oto'o.

Redshirt freshman JJ Peterson, who didn't arrive on campus until last September, will also garner plenty of attention this spring/summer.

But it could be junior linebacker Will Ignont who ends up having the biggest impact at the position for the Vols this fall.

The Alabama native, who has started two games during his career in Knoxville, totaled 47 tackles last season. Seven of those tackles came in his second start — the season finale against Vanderbilt.

This off-season, Ignont has reportedly slimmed down and taken on more of a leadership role within Tennessee's defense. With Darin Kirkland's status moving forward uncertain, and Peterson not participating in contact work, it could mean Ignont has a major role as an inside linebacker in 2019.

Jeremy Banks — Running Back

Jeremy Banks burst on to the scene last season with his hard nosed running style, but a propensity to lose the ball kept him from making a big impact as a true freshman.

The Cordova native ended up rushing for 185 yards in 11 games. At one point, Banks was moved to linebacker, but he's been moved back to running back for spring practice.

With a year of experience under his belt, I think we'll see Banks explore a more mature running style in 2019.

There's no doubt the young running back has the skills to be a dangerous running back in the SEC. At 6-foot-1/220 lbs, he's not an easy player to tackle. If he can get his ball security issues under control, and become a more patient runner, I think he'll go from an afterthought to an offensive weapon for the Vols.

And if not, he can always switch back to linebacker where he'll undoubtedly be one of the hardest hitters on the team.
