College Football Recruiting Rankings: Top 2015 Schools Post-National Signing Day

National signing day is finally in the books, and those schools that made the best haul over the 2015 recruiting cycle have bragging rights ahead of them.

There are more than a dozen impressive classes across the landscape of college football, but a couple of star-studded ones stand out. We won't know for sure how the stars translate onto the field for some time, but which schools finish atop the recruiting rankings is often a telling indicator of what's to come.

With that said, let's look at the top 15 schools atop the 247Sports composite team rankings after national signing day.

Top Classes

USC

Steve Sarkisian had about a month to assemble his first USC recruiting class, but he hit the ground running for his second class and turned it into one of the best in the land.

The Trojans' 2015 class gained so much steam on national signing day that it even trumped Alabama for No. 1 at one point before the Crimson Tide regained their spot. But it's safe to say they won't be disappointed with their haul.

They built it from the defense up, adding 10 players on the defensive side of the ball who ranked in the top 10 at their position nationally. Among them are three of the top six outside linebackers, adding No. 6 outside linebacker John Houston to the mix on signing day, as per ESPN College Football:

Their defensive haul continued through Wednesday, when they secured No. 5 defensive tackle Rasheem Green and also locked down prized cornerback Iman Marshall. The No. 4 overall recruit revealed his decision with the following music video from Bleacher Report:

While they beefed up the defensive side of the ball considerably, the Trojans obviously didn't forget about offense. And two of the most important players on that side of the ball are already on campus. No. 1 offensive guard Chuma Edoga and No. 6 pro-style quarterback Ricky Town are both enrolled for the spring.

Tennessee

Tennessee's 2015 class was all but wrapped up entering national signing day, but Butch Jones and Co. had their sights set on one final flip to complete the class.

The stars seemed to be aligning for a late commitment from No. 3 offensive tackle Drew Richmond, who visited Knoxville over the weekend and followed it up by de-committing from Ole Miss. On Wednesday, he made the switch official, per Tennessee Football:

It'd be hard to deny the Volunteers' place among the top classes of 2015 even without Richmond. But according to Jones and the Tennessee staff, securing one of the top players at a position of need couldn't have been bigger.

"It completed the class," Jones told the Chattanooga Times Free Press' Patrick Brown. "We get back to improving our overall athleticism in the offensive front, and Drew obviously does that. ... I'm excited because he's going to add to the offensive line."

Of course, Tennessee already made quite the haul. It locked down No. 2 defensive tackle Kahlil McKenzie early on, who helped spearhead the peer-recruiting efforts to help make late flips like Richmond's happen.

With 29 total signees and 16 of them boasting 4-star ratings or more, Jones has compiled yet another loaded recruiting class to bolster the talent level in Knoxville.

Alabama

Few schools had as quiet of a national signing day as the Alabama Crimson Tide, but nobody finished with a more stacked recruiting class.

Head coach Nick Saban and crew finished atop the recruiting rankings again, and once again, it's a heap of 5-star talent that helped to get them there. They locked down No. 1 receiver Calvin Ridley, No. 4 cornerback Kendall Sheffield and No. 1 running back Damien Harris long before signing day.

While finishing atop the 247Sports rankings is a feat in itself, ESPN's Adam Schefter noted how they dominated the ESPN rankings as well:

It's just another year, another recruiting championship for Alabama, as Bleacher Report's Barrett Sallee noted:

Recruiting rankings only mean so much, but they've never been validated more so than at Alabama. Its recruiting dominance has seen a direct correlation with the team's continued on-field prominence, and Saban has seemingly stocked the cupboard again.

What makes Alabama truly great is how it's able to reload. Notice how the Tide cleaned up with the top recruits at receiver and running back, coincidentally at the same time they look to replace star wideout Amari Cooper and running back T.J. Yeldon.
