Signing Day Roundup: Deontay Greenberry leaves Irish at the altar for…Houston?

Follow the day's most anticipated signings with Rivals' announcement watch, updated throughout the day.

• Swag of the Day. Oxford, Ala., linebacker Kwon Alexander only has four stars from Rivals, but I'm going to go ahead and give him five in honor of the LSU-themed suspenders and bow tie ensemble he wore this morning to commit to the Tigers on national television. If football doesn't work out, I recommend Kwon look into a future in blipster fashion.

In fact, those suspenders were about as good as it got for Les Miles: With Shreveport linebacker Torshiro Davis' overnight defection to Texas and Geismar safety Landon Collins' loyalty to Alabama, LSU incredibly failed to sign any of the top four prospects in the state of Louisiana.

•Stunner! Record-breaking Fresno, Calif., wide receiver Deontay Greenberry pulled the rug out from underneath everyone this morning by signing with Houston over Notre Dame, an out-of-nowhere switch after eight solid months committed to the Fighting Irish. It's an ironic one, too, considering it was Greenberry who swore fidelity to ND in December when his cousin, Tee Shepard, appeared to be flirting with USC.

Instead, it was Shepard who wound up enrolling in South Bend last month, and Brian Kelly who's left to wonder how he let one of his biggest fish get away to Conference USA. (Cue Irish fans alleging unreported academic issues in three... two... one...)

• Fourth time's the charm. For most of his high school career, Westlake Village, Calif., wide receiver Jordan Payton was verbally committed to USC. Then, last month, he used the Army All-America Game in San Antonio as a platform to pledge his loyalty to Cal. Tuesday night — less than 24 hours before he planned to put his name on a letter of intent — he shunned the Bears in favor of Washington. And when the moment of truth finally arrived this morning, he woke up and faxed his signature to… UCLA, of course. Payton looks like a catch — he's a top-100 prospect with solid size and speed — but does Jim Mora know why the rest of the Pac-12 locker room is sniggering behind his back?

At any rate, Payton is only one piece of the puzzle at a position of desperate need for one of the league's most low-octane offenses: The Bruins also managed to flip two other receivers overnight, unexpectedly inking three-star Kenneth Walker (another ex-Cal commit) and four-star Javon Williams out of Arizona.

• Big ones. Stanford is losing a pair of All-American offensive linemen to the NFL, but the pipeline is delivering at full steam: With the addition of five-star tackle Andrus Peat out of Tempe, Ariz., the Cardinal have signatures from five O-linemen graded as four stars or higher by Rivals, with another five-star — undecided tackle Kyle Murphy — still very much on the radar. Along with Peat and Graham Shuler on the outside, Stanford also has two guard prospects on the inside, Brandon Fanaika and borderline five-star Joshua Garnett, rated among the top 10 guards in the incoming class. Update, 4:31 p.m. ET: Kyle Murphy is now in the fold, as well, giving the Cardinal two (and with Garnett, basically three) five-star offensive linemen in a single class. Whoever's starting at quarterback there in two years should never have to wash his jersey.

• Five-Stars On the March! Top-ranked cornerback Tracy Howard is going to Miami. … St. Petersburg, Fla., defensive end Dante Fowler Jr. spurns the Seminoles for the Gators at the last second. … And Valdosta, Ga., linebacker Josh Harvey-Clemons has verbally committed to Georgia, but hasn't made it official.
