Professional career
Pre-draft
In June 2016, Feeney was labelled the “best interior offensive lineman” prospect in the 2017 NFL draft by NFL analyst Lance Zierlein.[15] After completing his senior season in 2016, Feeney entered the draft and was projected by NFL draft experts and scouts to be a second round pick. He received an invitation to the NFL combine and completed all of the required combine and positional drills. On March 31, 2017, he participated at Indiana's pro day, along with Devine Redding and six other prospects. He opted to only perform positional drills for scouts and team representatives from 27 NFL teams looked on, including offensive line coaches from the Philadelphia Eagles, Buffalo Bills, Miami Dolphins, and Detroit Lions.[16] He was ranked the second best offensive guard prospect in the draft by NFLDraftScout.com, ESPN, and NFL analyst Mike Mayock.[17]
The Los Angeles Chargers selected Feeney in the third round (71st overall) of the 2017 NFL Draft.[21] Feeney was the second guard the Chargers selected in the draft, behind Forrest Lamp (second round, 38th overall).[22] He was also the fourth offensive guard and the fifth interior offensive lineman selected in the draft.
On June 2, 2017, the Los Angeles Chargers signed Feeney to a four-year contract worth $3.7 million, with a $924,632 signing bonus.[23]
