Baker signed with Georgia on national signing day, despite speculation that he would sign with Texas based on a tweet he sent out the night before.[2] As a true freshman at Georgia in 2015, Baker played in 11 games. During the 2016 season, Baker was injured in a game against Vanderbilt. He recovered, but was later injured against Georgia Tech.[3] Following the 2017 season, Baker was named to the Second-team All-Southeastern Conference.[4] Baker considered declaring for the 2018 NFL Draft, but he ultimately elected to return to school for his senior year.[5]
Baker was one of the best cornerbacks in college football in his senior season. He allowed only 175 yards and a 40.2 NFL passer rating to opposing receivers in 2018, which both ranked in the top 5 of all draft eligible cornerbacks with a minimum of 300 coverage snaps. He was named a consensus 2018All-American and won the Jim Thorpe Award, awarded to the best defensive back in college football. Over his entire 4-year tenure at Georgia, Baker only allowed one touchdown.[6] Baker entered the 2019 NFL Draft as one of the best cornerback prospects.
Baker was selected by the New York Giants in the first round, 30th overall, of the 2019 NFL Draft.[10] The Giants had traded up with the Seattle Seahawks to acquire the pick giving up their 37th, 132nd and 142nd picks.[11]
Baker was placed on the commissioner's exempt list on July 27, 2020, following his May 2020 arrest.[12] The Giants waived Baker on September 8, 2020.[13]

On May 14, 2020, a warrant was issued for Baker's arrest under charges of armed robbery and aggravated assault with a firearm, along with Quinton Dunbar of the Seattle Seahawks.[24] The following day, Baker's lawyer issued a statement claiming that he was in possession of multiple affidavits allegedly exonerating his client.[25] The two allegedly robbed guests at gunpoint during a house party and had turned themselves in to the police by May 16.[26][27] On August 7, 2020, Baker was charged with four counts of robbery with a firearm.[28] There was evidence suggesting the alleged victims accepted $55,000 in exchange for changing their story in regards to Dunbar.[29] On November 16, 2020, the charges against Baker were dropped.[30][31]
