I don't know the ins and outs of the what was taking place in Florida, but from what I recall, Florida was trying to remove the term "athlete" in the athletic training practice act. That would allow athletic trainers to treat people of all ages that still fit into the professional background of an athletic trainer. In many states "athlete" is defined as one who is on a sports team. But that would exclude individuals such as marathon runners, military personnel, etc from being able to seek treatment from a Certified Athletic Trainer. Physical Therapists have fought this long and hard in many states. And unfortunately (for some) they have been successful. This limits the patient's ability to seek his/her desired treatment and it limits the athletic trainer's ability to treat patients.
Another thing Florida has done in some places is to eliminate Athletic Trainers and instead replace them with "First Aid Coordinators." This is downright scary and I'm surprised it hasn't led to a massive lawsuit. I'm sure at some point it will. South Carolina is another state that requires a "first responder" but that person also has very little training compared to that of the Certified Athletic Trainer. For far too long, schools, states, parents, and other healthcare providers have regarded athletic healthcare as an afterthought.

I know this next paragraph is likely to set off some hatred or whatever. But I think the argument could be made that PT is restricting the practice of Athletic Trainers. By clinics hiring Athletic Trainers in outreach positions, many times those ATs are severely limited in what they are allowed to do, they make pennies, and are expected to refer all rehabilitation back to the clinic to make a profit. PTs don't like being controlled by MDs through POPTs, but they seem to be just fine with that referral method when the PTs are the ones on top. I believe this is undercutting the Athletic Training profession because the clinics pay much less than what the schools are paying the clinics, but the schools are saving a significant amount of money to get what they think they need. Again, this goes back to the afterthought of athletic healthcare...
