Alabama's stellar Class of 2013 added another important piece on Friday.
The Sandalwood High School star is rated as a 4-star prospect in the 247Sports.com Composite and rated as the No. 29 prospect in the entire country.
Walker chose the Tide over several schools, but his commitment isn't necessarily set in stone. He told ESPN.com that he will still listen to other schools and will take all five of his official visits to Alabama, Auburn, LSU, Tennessee and USC.
He's a perfect fit for Saban and defensive coordinator Kirby Smart's 3-4 defense.
He's big enough to be a force in the defensive end spot in that system, just like Tide defensive lineman Marcell Dareus was.
That's a big-time comparison, but it's a worthy one.
He's strong, quick and fast, which is a good combination for Walker—especially if he wants to play immediately at Alabama.
Expect him to contend for early playing time.
Alabama has 4- and 5-star prospects littered throughout its roster, but if there's one thing Saban is known for, it's for playing his best players regardless of seniority.
The Crimson Tide will likely start seniors Damion Square and Quinton Dial at the two defensive end spots around nose guard Jesse Williams, so there will be spots available for Walker on the depth chart when he arrives on campus.
I hate this cliche, but Alabama doesn't rebuild, it just reloads.
The commitment of DeMarcus Walker is further proof of that.
