New Tigers RB commit Armoni Goodwin.

First-year Auburn running backs coach Cadillac Williams has his first running back commit. And, it's a big one.

But it's not from a 2020 recruit.

Instead, it came Wednesday afternoon from 4-star 2021 back Armoni Goodwin of Hewitt-Trussville (Ala.). He's the No. 2 running back in the country in the rising junior class for 247Sports.

Goodwin made his announcement via Twitter.

Goodwin, who is listed at 5-feet-8, 190 pounds, is commitment No. 1 in the 2021 class for the Tigers.

"Well, first off Armoni is a great kid," said Hewitt-Trussville coach Josh Floyd. "He's a great kid that works hard. He's super explosive and has legit speed. He's definitely one of the fastest, if not the fastest kid I've ever coached. He also has incredible balance and that's the thing about him. -- he can take a hit and stay up."

According to Floyd, Williams played a huge role in Auburn landing Goodwin’s verbal.

“I think he did a great job on him,” Floyd said. “I met Cadillac for the first time during the spring recruiting period. He’s got a big name obviously with Auburn ties. People know him and families know him. Armoni’s mom knew who he was and that made a big difference. I know he has developed a real good relationship with Armoni.”

Here is 247Sports' evaluation of Goodwin:

"Short, compact build. Is filled out with muscle mass from top to bottom relative to this stage in development. Has the thick lower body of a sprinter. Has long possessed high-end top speed, running a sub 11 second 100-meter time as a freshman in high school. That top end speed transfers over to the football field. Consistently rips off long runs and pulls away from defenses with ease. Has outstanding pace once he's in the open field. Had a productive sophomore year, averaging nearly 7 yards per carry. Dangerous on screens, draws, misdirection plays that can get him in space. Runs with nice lean and contact balance, particularly for a smaller back. Shows ability, but will need to continue improving his production as a pass catcher to fully maximize his value at the next level. Projects as a contributor and potential feature back for a Power Five program with the upside of developing into a high NFL Draft pick."

Goodwin is coming of an extremely productive sophomore season. He carried the ball 212 times for 1,458 yards and 15 touchdowns. He also caught six passes for 45 yards.
