Joey O'Brien

Physical Profile

Rare length for the position: measured 6-4, 180 with 32.5-inch arms and 9.75-inch hands at the Rivals Five-Star camp as a junior, now listed 6-5, 200-203 on Notre Dame's roster after one offseason in a college program. That 20-plus pound gain matters because the primary knock in his 247Sports evaluation was a streamlined frame and only adequate foot speed for an outside alignment. His catch radius, wingspan and high-point ability are wide-receiver traits (86 catches, 1,249 yards, 18 TDs as a senior) transplanted onto a deep safety, which is why evaluators comp him to Justin Simmons. He is a long-strider with legitimate center-field range rather than a twitchy slot-corner type, and his frame can carry 210-215 without losing that range.

Play Style

On film he plays like a receiver who was handed the deep middle. He baits quarterbacks by disguising his depth, closes with long strides on throws over the middle, and finishes interceptions rather than pass breakups because of his hands. He is comfortable as a single-high center fielder using his top gear, but is arguably more dangerous lurking underneath at 10-12 yards where his reach and vision let him undercut in-breaking routes. He tackles high but wraps, and he uses his length to keep blockers off his frame in the alley. Early Notre Dame fall camp footage (an interception shared by the program's official account) showed the same ball-tracking skill translating immediately against college receivers.

Strengths

• Elite ball skills and route recognition: 4 interceptions in the regular season plus 3 more in the PIAA 6A title game, including a 94-yard pick-six, and 18 receiving touchdowns on offense. He reads quarterback eyes and route stems early enough to arrive before the ball does.
• Length as a weapon in coverage and at the catch point: 32.5-inch arms and a near 6-5 frame let him erase throwing windows on posts and seams and win contested balls that shorter safeties can only break up.
• Instinctive angles and tackling willingness: 247Sports credited him with efficient angles in both coverage and run support, and he logged 50 tackles as a senior despite being the offense's primary weapon. He shows up in run support rather than lurking exclusively as a ball-hawk.
• Proven big-game production: Gatorade and MaxPreps Pennsylvania Player of the Year, led La Salle to 13-1 and a state championship, and delivered his best performance (10 catches, 99 yards, 3 INTs) on the championship stage.

Areas to Improve

• Short-area quickness and change of direction: evaluators questioned whether his foot speed holds up in man coverage against slot receivers, so Notre Dame is developing him as a deep safety and robber rather than a boundary corner. Transition footwork out of his pedal is the key technical refinement.
• Functional strength and durability: he arrived at 180 pounds, and a left-leg injury in the 2026 Blue-Gold Game required surgery. He was full-go by August, but adding lower-body mass and proving he can absorb a full Power Four season are the remaining questions.
• Full-time defensive reps: splitting snaps at receiver in high school limited his exposure to complex coverage rotations and disguised fronts. His run-fit discipline and communication in a two-high shell are still being built.

College Projection

Rotational safety as a true freshman in 2026 behind Adon Shuler and Brauntae Johnson, with dime and third-safety packages plus special teams as the entry point. Notre Dame media and staff have floated him as a potential starter as early as this season if injuries hit. The expected arc is a full-time starter by 2027 as a sophomore, three-year starter, and a candidate to leave after his junior season. His receiver background gives Notre Dame a fallback if defensive development stalls, but every indication is that he stays at safety.

NFL Outlook

High-end NFL draft profile. A 6-5, 205-plus safety with 32.5-inch arms, verified ball production and a Justin Simmons comp checks the boxes NFL teams pay for at the position. If his testing numbers land in the 4.5 range and he stays healthy, he projects as a Day 1 to early Day 2 pick with a floor as a big-nickel/dime coverage specialist. The risk factors are the long-speed question against NFL slot receivers and the 2026 leg surgery, which scouts will track closely across his medicals.

Best Fit

He committed to the right kind of scheme. A defense that uses split-safety looks and rotates its safeties between deep-half, robber and overhang roles maximizes his instincts and length while hiding any short-area limitations in man coverage. Notre Dame under Marcus Freeman fits that profile and has a track record of developing long, versatile defensive backs into NFL starters. A program that asked him to play boundary corner full-time, or a pure single-high system that lives on 4.4 range, would be a worse fit.
