Raimann grew up in Steinbrunn, Austria.[1] He began playing American football at the age of 14 for the Vienna Vikings' youth team.[2] Raimann attended Ballsportgymnasium in Vienna, a publicly funded upper secondary school for elite competitive athletes,[3] and attended Delton-Kellogg High School in Delton, Michigan as an exchange student for his junior year.[4]
While on exchange, Raimann lived with a host family that included a former Central Michigan University football player, Rollie Ferris, and his future college teammate, Tyden Ferris.[5] He returned to Austria after the year and completed his compulsory service in the Austrian military after graduating from Ballsportgymnasium Wien.[1] Raimann committed to play college football at Central Michigan after his military service was completed.[6]
College career
Raimann played tight end during his first two seasons at Central Michigan. He caught 20 passes for 164 yards over the course of his first two seasons.[7] He was moved to the offensive tackle position after his sophomore year and started all six of the Chippewas' games during its COVID-19-shortened 2020 season.[4] In 2021, Pro Football Focus named Raimann their Offensive Player of the Year for the Mid-American Conference.[8][9]
According to Colts beat writer Nate Atkins of the Indianapolis Star, the team counted on moving veteran lineman Matt Pryor to the critical left tackle spot in 2022.[13] This experiment proved a debacle, however, and in Week 5 Raimann was thrust into the starting lineup by head coach Frank Reich.[13] Raimann would start 11 of the final 13 games of his rookie year.[13]
During the off-season, Raimann worked adding strength and mass to his 6'6" frame, putting on 15 pounds.[13] He was named the starting left tackle from the opening week of the 2023 season and would play in 15 games during the year.[13] Raimann's performance was greatly improved during his sophomore season, with Sports Info Solutions analysis indicating that his rate of quarterback sacks allowed fell from 2.2% as a rookie to 1.2% in year two, with his percentage of blown run blocks similarly dropping from 3.7% to 2.1%.[13]
Moreover, Raimann's number of penalties also declined in 2023 versus his rookie 2022 campaign — from 7 accepted flags to 4[14] — despite his participation in 180 more passing snaps during his second season.[13]
