Guards/Centers

Alabama left guard Tyler Booker: Arguably the top interior lineman prospect, the 6-foot-5 four-star high school recruit's 40-yard dash, broad jump and three cone should be monitored closely. 

According to NFL.com's Combine IQ (CIQ), in the 40, 5.3 seconds is considered good and 5.1s is elite for guards, 8-feet-6 is good and 9-feet-4 is elite in the broad jump and a 7.85s three-cone drill is good while anything 7.45s or under is elite.

Iowa right guard Connor Colby: The 6-foot-6 four-year starter looks to join a long lineage of Hawkeyes linemen who've excelled in the NFL. Ravens center Tyler Linderbaum and Buccaneers tackle Tristan Wirfs are among the recent former Iowa standouts to successfully make the leap.

Cincinnati right guard Luke Kandra: Pro Football Focus credited the 6-foot-4 Bearcats lineman with only allowing eight pressures (and zero sacks) in 428 pass-rush situations in 2024. Per CIQ, he has the third-highest production score (77) among guards at the 2025 combine.

Texas center Jake Majors: The Longhorns are well represented at the combine with 14 participants. Majors (6-foot-3) is one of the top centers, having played 1,042 total snaps in 2024. Over the past two seasons (2023-24), he allowed 22 total pressures and zero sacks in 1,060 pass-rush opportunities.

Ohio State center Seth McLaughlin: On Saturday, while recovering from a ruptured Achilles, McLaughlin discussed "reassuring" front offices about his long-term prognosis at the combine. The Alabama transfer only allowed one sack in five collegiate seasons. (h/t PFF)

USC center Jonah Monheim: As a fifth-year senior, Monheim (6-foot-5) allowed zero sacks for the Trojans in 2024. Monheim also played left tackle (781 snaps), right guard (387 snaps) and right tackle (1,157 snaps) during his collegiate career, making him one of this year's most versatile linemen.

Georgia right guard Tate Ratledge: The 6-foot-6 veteran started the past three seasons for the Bulldogs, allowing only two sacks. And sporting a magnificent mullet, Ratledge has the best hair in Indy. (Video h/t A to Z Sports' Travis May)
