Under Armour All-America Game 2015: Top Recruits to Watch During Showcase

College football's future will be on display Friday at Tropicana Field. 

The Under Armour All-America Game is meant to be an entertaining exhibition that rewards many of the country's best young prospects for standout senior seasons. But oftentimes it becomes a strong indicator of players who will be making an impact on college campuses in about nine short months. 

During last year's game, Leonard Fournette, Speedy Noil, Dalvin Cook and Travis Rudolph all stood out, and each of them has relayed that success into impressive true freshman campaigns.

Let's take a look at some candidates to follow a similar path in 2015.

Date: Friday, Jan. 2

Time: 4 p.m. ET

Location: Tropicana Field, St. Petersburg, Florida 

TV: ESPN2

Live Stream: WatchESPN

Byron Cowart, DE, Undecided

This gives you a good idea of what Byron Cowart is capable of, via Rivals' Mike Farrell:

Goodness. That would be 4-star offensive tackle and top-100 recruit Keenan Walker getting pancaked like he was on roller skates. 

"I'm just trying to show people that I'm violent and dominant and aggressive and relentless," said Cowart, via Wesley Sinor of AL.com. "If I say I look up to guys like (Ndamukong) Suh and (Nick) Fairley, I have to play just like them."

The 5-star uncommitted defensive end from Florida is a tantalizing blend of size, speed and power. Defensive players don't always get a ton of recognition in exhibition games like this, but an edge-rusher with Cowart's kind of explosion could easily put on a show. 

Keep a very close eye on him. 

Damien Harris, RB, Undecided

This year's running back class isn't quite as strong as the previous year's, which featured Fournette as the No. 1 player in many circles. But that doesn't mean it's void of talent. 

Damien Harris, in particular, is an exciting prospect. He's a strong runner with terrific vision, game-breaking speed and the versatility to make plays as a pass-catcher, as ESPN's Tom VanHaaren shows:

247Sports' JC Shurburtt put it simply:

With quarterbacks and wide receivers not always possessing great chemistry after only a week of practice, these games often feature the running backs. Harris, who is extremely skilled and explosive, should see a lot of touches both in the running game and as a receiver. 

Calvin Ridley, WR, Alabama

A 5-star wide receiver committed to Alabama, Calvin Ridley was "virtually unstoppable" during practice against top cornerback Iman Marshall, according to 247Sports.com. 

That's not really a surprise. Although he doesn't possess immense size (6'0", 170 pounds), he is long, knows how to create separation and has the speed to either take the top off a defense or take the ball to the house if he gets any kind of lane.  

When it comes down to it, Ridley is a true playmaker, and one way or another, he's going to find a way to put on a show. While most of his action will likely come in the passing game, he could also have an impact on returns, per Rivals' Andrew Bone:

Either way, Alabama fans are going to get a glimpse of a player who could very easily prove key in replacing the production of Amari Cooper.
