Groton (Mass.) Lawrence Academy four-star running back AJ Dillon has flipped his commitment to Boston College. The 6-0, 228-pounder announced his decision via Twitter.

The No. 21 running back nationally and top player in Massachusetts released a long, well-thought out statement with coacheslunch.com on why this decision was the best move for him.

“I believe that coach Harbaugh and the University of Michigan have something very special being put together. Especially with the incoming 2017 class, assistant coaches, and the Michigan fan base which is in my opinion second to none. I’m humbled by the support that the coaches and fans have given me since my commitment last March. I love the University of Michigan and everything that the school stands for from academics to athletics. However, this is a selfish decision and after meeting with my family I feel like my attendance at Boston College for the continuation of my athletic and academic career is the best place for me. To the coaches, players, and especially class of 2017 who I’ve grown close to I wish nothing best. I’ll be watching when you win the next few national championships. I have nothing bad to say about the University of Michigan, Go Blue.

"Being from Connecticut going to a private boarding school in Massachusetts there was a bit of unease. But Lawrence Academy, Boston, and the rest of Massachusetts have always welcomed me with open arms and have supported me more than just off the field. I look forward to representing the city of Boston, state of Massachusetts, my family and everyone in New London, CT. I believe the Boston College program is on the rise and I feel like there is something to be said about being from here, and being part this movement. I’ve developed great relationships with the coaches and players at Boston College and am excited to be a part of the Eagles family and uphold that BC tradition. #DecideToFly

"I’m aware there are a lot of people that aren’t going to agree or understand my decision, but I just ask that you respect that I believe is best for me and my family.

"*Also I will not be doing any interviews for awhile, Thank you*"

Michigan still holds commitments from Los Lunas (N.M.) four-star running back O'maury Samuels and Loganville (Ga.) Grayson three-star running back Kurt Taylor. The Wolverine staff is also aggressively pursuing the nation's top overall prospect, Antioch (Calif.) five-star running back Najee Harris.

Other running backs are also still on the radar a bit according to a recent positional Hot Board.
