USC QB Husan Longstreet Joins LSU for Bold Move Under Lane Kiffin

Husan Longstreet's move from USC to LSU adds another layer of intrigue to Lane Kiffins rapidly evolving quarterback room in Baton Rouge.

Husan Longstreet Heads to LSU: Former USC QB Joins Lane Kiffin’s Quarterback Room

Husan Longstreet is on the move. The former Corona Centennial standout and one-time USC backup quarterback has officially signed with LSU, announcing his decision on social media Wednesday afternoon. The move comes just days after Longstreet reportedly visited Baton Rouge, and it adds another intriguing layer to what’s quickly becoming a crowded and competitive quarterback room under new Tigers head coach Lane Kiffin.

Yes, that Lane Kiffin - the former USC assistant and head coach who made headlines once again by leaving Ole Miss to take the reins at LSU. And he’s wasting no time reshaping the roster. With just two days left in the current transfer window, Kiffin has now brought in three quarterbacks via the portal, including Longstreet.

Joining Longstreet in LSU’s revamped QB room are Landen Clark, a three-star transfer from Elon, and Sam Leavitt, a high-profile five-star pickup from Arizona State. Leavitt arrives with one of the biggest NIL valuations in the portal - a reported $3.1 million - and brings with him a solid sophomore campaign: 1,628 passing yards, 10 touchdowns through the air, and another 306 yards and five scores on the ground. If there’s a quarterback battle brewing in Baton Rouge, Leavitt figures to be Longstreet’s top competition.

But don’t count Longstreet out.

While he doesn’t yet have the same college résumé as Leavitt, Longstreet’s upside is undeniable. Injuries limited his senior season at Centennial, but when he was on the field, he was highly efficient - completing 66.1% of his passes for 1,641 yards and 19 touchdowns, while also rushing for nearly 500 yards and six more scores. That dual-threat ability was part of what made him one of the top high school quarterbacks in the country.

At USC, Longstreet spent his true freshman season behind Jayden Maiava, seeing limited action in four games. But when he got on the field, he made the most of it.

Against Missouri State, he was perfect through the air - 9-for-9 for 69 yards and a touchdown - and added 54 rushing yards and two scores. He followed that up with a 4-for-6, 34-yard passing performance against Georgia Southern.

Not massive numbers, but enough to flash the poise and athleticism that made him a five-star recruit.

Longstreet’s journey to LSU has already had a few twists. Once committed to Texas A&M, he flipped to USC in November 2024 - a dream destination for the Southern California native who had grown up wanting to wear the cardinal and gold since he was 9 years old. The Trojans welcomed him with open arms, even choosing him over fellow five-star Julian Lewis, who ultimately committed to Colorado.

Lincoln Riley, USC’s head coach, was all-in on Longstreet at the time. After Longstreet’s commitment became public, the two connected on FaceTime, where Riley reportedly told him it was “the most excited he’s been in a while.” But things change quickly in college football.

With Maiava announcing last month that he’ll return for his redshirt senior season after leading the Big Ten with 3,711 passing yards, Longstreet began exploring his options. It became clear that his path to significant playing time at USC would be delayed, and with the portal closing soon, he made his move.

Now, Riley is left with Sam Huard and incoming four-star Jonas Williams as Maiava’s backups. And if USC wants to add another arm, time is ticking - the portal shuts Friday.

As for Longstreet, he’s stepping into a new opportunity with LSU - and into a quarterback room that’s suddenly one of the most intriguing in the country. Kiffin has his hands full sorting out the depth chart, but he’s also got an embarrassment of riches at the position.

Longstreet may not have the experience of Leavitt or the immediate starting path he hoped for at USC, but he’s got the tools. And under Kiffin, a coach known for his quarterback development, that could be just what he needs to take the next step.

One thing's for sure: the QB battle in Baton Rouge just got a lot more interesting.
