5 Mike Kafka replacements the Giants should already be thinking about

3. Ohio State OC Brian Hartline

One of the top OC candidates from the collegiate ranks is Ohio State's Brian Hartline. The 36 year old is a Canton, Ohio native and OSU alumnus, where he played wideout from 2005 through 2008. Hartline went on to play for the Miami Dolphins for five years and spent a short period with the Cleveland Browns before going on to coaching.

Since 2017, Hartline has been a member of Ohio State's coaching staff, where he served as an offensive quality control assistant before taking over as wide receivers coach when the team dismissed Zach Smith. In 2020, 247Sports named Hartline "National Recruiter of the Year," - a year later, he was promoted to passing game coordinator on top of his responsibilities as wide receivers coach. Before this season, he was promoted to the Buckeyes' offensive coordinator.

Not only has Hartline emerged as one of the nation's top recruiters, but he is also an elite talent developer, especially regarding wideouts. Several of the league's best young wide receivers have come out of OSU during Hartline's tenure in Columbus, including Chris Olave, Garrett Wilson, Jaxon Smith-Njigba, and soon-to-be Marvin Harrison Jr.
