49ers hosting USC safety Calen Bullock on pre-draft visit

Bullock registered 63 tackles, seven passes defensed, two interceptions, and a touchdown through 12 game appearances as a senior in 2023, per Sports Reference. Over his collegiate career spanning three seasons, he amassed 151 tackles, 15 passes defensed, nine interceptions, and two touchdowns.

Bullock started 26 games for the Trojans over the past two seasons. His 82.5 overall Pro Football Focus grade in 2022 was a career high. However, that mark dropped to 71.5 in 2023 while playing 845 defensive snaps. Bullock currently ranks 81st on Pro Football Focus' big board.

"Long and athletic with a series of feast-or-famine plays all over the tape," Lance Zierlein wrote in his NFL.com scouting report. "Bullock can be scary good in coverage and scary bad as a run defender. He has the range to play single-high safety, the athleticism to line up over the slot and the ball skills to chalk up impressive on-ball production.

"As a run defender, Bullock's poor recognition, missed run fits and bad angles to the football cost his team chunk plays and touchdowns. He won't always see or process the game clearly, but the athleticism and playmaking talent are hard to overlook. He's young and talented, and if he runs well enough, there might be a team more interested in his skill set as a cornerback than as a boom/bust safety."

At the NFL Scouting Combine, the 6-foot-2, 188-pound Bullock recorded a 40-yard dash time of 4.48 seconds.
