Just days before the biggest event in football, and probably all of sports, President Barack Obama shared an opinion that might dampen the enthusiasm of the NFL.

In an interview that will appear in the Feb. 11 issue of The New Republic, Obama said: “I'm a big football fan, but I have to tell you if I had a son, I'd have to think long and hard before I let him play football.”

The two head coaches for Sunday's Super Bowl, brothers John and Jim Harbaugh, don't agree with the president.

“Football is a great game,” Baltimore Ravens coach John Harbaugh told the Denver Post. “And anybody who's played the game knows what a great game it is, what it provides for young people, what it provided for people like me. I think it's a huge part of our educational system in our country and it's going to be around a long time.”

Said San Francisco 49ers coach Jim Harbaugh: “Well, I have a 4-month old, almost 5-month old son — Jack Harbaugh — and if President Obama feels that way, then there will be a little bit less competition for Jack Harbaugh when he gets old.”

Concern about the violence of the sport and the lasting harm to players continues to garner attention. Studies linking football to long-term degenerative brain damage and suicides of former players have many parents questioning whether they should let their children play the game.

Just as there is disagreement among current and former players, coaches, and fans on this issue, there also is debate among healthcare professionals and sports medicine experts. I polled some experts for their opinions:

Dr. Wendy Sue Swanson, pediatrician at Seattle Children's Hospital:

“If it were my child, I'd never let them play football. No way. For my boys, the risks are too large, the sentiments too cruel, and the gains simply not worth it. There are plenty of other sports teams out there to grow, exercise, form friendships, and excel.”

Dr. Steve A. Mora, orthopaedic sports medicine surgeon in Orange County, California:

“Playing football certainly increases the chances of extremity injuries as well as concussions. I've seen so many football injuries in my career that it really does make me think twice about letting my kids play. At the same time, my viewpoint is skewed because I only see the injuries. Overall most kids on a football team remain injury free. So yes, if my children were passionate about football, I would allow them to play as long as they were not getting repeatedly injured. I would not allow my children to play if they suffered a single concussion.”

Dr. Ford Vox, brain injury specialist at the Shepherd Center in Atlanta:

“If I had a son, I would steer him towards other sports. The key issue is whether children can really give informed consent for sport. I don't think they can, so parental judgment will have to supplement the child's preferences. Once a kid is mature enough to take on responsibilities like driving and voting, if they remained passionate about football, I'd make sure they know the apparent risk, but they'd receive my support in their choice.”

Dr. Andrew Blecher, primary care sports medicine physician at the Southern California Orthopaedic Institute:

“Football has much to offer but also comes with significant risks. When he is old enough and mature enough to understand these risks and make an educated decision then I would let him play. However, I truly believe that the long-term cognitive decline consequences of playing football are not due to a few concussions but rather due to the repetitive sub-concussive hits to the head that occur on a daily basis. Therefore, I would strongly recommend that he not play lineman, linebacker or running back.”

Dr. Christopher Geary, orthopaedic surgeon and Chief of Sports Medicine at Tufts Medical Center in Boston:

“I'm sure a lot more data will come out before I am confronted by this decision, and hopefully effective new safety measures will be instituted. Right now, though, I would say that I would not intentionally steer him to football but I would not specifically prohibit him from playing. Not that I wouldn't be nervous every time he took the field to some degree, but if he came to me and wanted to play I would let him.”

Dr. Jonathan Edwards, Chief of Neurology at the Medical University of South Carolina and Director of the MUSC Sports Neurosciences Program:

“The short answer is no. I enjoy watching football, but I think the current state of the game is that hard hitting, hard tackles, head injuries, and other chronic residual ailments are so commonplace that I would steer them to other sport options. There has been some progress in terms of equipment, changes in rules, shifts in focus in coaching, but for my own kids, I would prefer other ways for them to get exercise and learn teamwork.”
