OWINGS MILLS, Md. — Joe D’Alessandris, whose nearly half-century of coaching offensive linemen eventually brought him to four different NFL teams, has died. He was 70.

The Baltimore Ravens, D’Alessandris’ employer since 2017, announced that he died Sunday. He was hospitalized earlier this month with an unspecified illness, and that caused him to step away from his duties as the team’s offensive line coach.

Coach John Harbaugh said at the time that D’Alessandris had had surgery earlier this summer and experienced complications.

“Our hearts ache with grief and sadness upon learning of coach Joe D’Alessandris’ passing early this morning,” the team said in a statement. “‘Joe D.’ lived a life of boundless faith, love, devotion and inspiration. As a husband, father, grandfather, friend and coach, Joe made every individual he encountered truly feel like they were the most important person in the world.”

Born April 29, 1954, in Sewickley, Pennsylvania, D’Alessandris coached in the CFL and the World League — as well as at several colleges — before reaching the NFL ranks. He was an assistant with the Kansas City Chiefs, Buffalo Bills and San Diego Chargers before settling in with the Ravens under Harbaugh.

“Coach ‘Joe D.’ was a man of integrity and a man of faith. He made us all better,” Harbaugh said. “He was our reader at team Mass, and he was loved by all here. He was a great coach and a good man — the kind of person who you are honored to have as a friend. He raised three incredible, beautiful daughters, and he was a most loving husband. His grandkids also adored him. I admired him, loved him and am going to miss him, because ‘Joe D.’ was a joy.”

D’Alessandris played at Western Carolina and began his coaching career there as a graduate assistant in 1977. His other college coaching stops included Livingston University, Memphis, Tennessee-Chattanooga, Samford, Texas A&M, Pittsburgh, Duke and Georgia Tech.

The Baltimore Ravens community is mourning the loss of Offensive Line Coach Joe D’Alessandris, who passed away at the age of 70. D’Alessandris, who had been with the Ravens since 2017, was known for his dedication to the game and his ability to develop and mentor young players.

D’Alessandris had a long and successful career in coaching, with stints at various colleges and NFL teams before joining the Ravens. He was highly respected by his peers and players alike for his knowledge of the game and his passion for teaching.

During his time with the Ravens, D’Alessandris played a key role in the development of the team’s offensive line, helping to mold them into one of the top units in the league. His attention to detail and commitment to excellence were evident in the performance of his players on the field.

In addition to his coaching abilities, D’Alessandris was also known for his kindness and generosity off the field. He was beloved by his players and colleagues for his positive attitude and willingness to help others.

The Ravens organization has expressed their condolences to D’Alessandris’ family and friends, as well as their gratitude for his contributions to the team. Head Coach John Harbaugh described D’Alessandris as a “great coach and an even better person” and stated that he will be greatly missed.

D’Alessandris’ legacy will live on through the players he coached and the impact he had on the game of football. His dedication to his craft and his ability to inspire those around him will not be forgotten. Rest in peace, Coach D’Alessandris.
