On Sept. 4, Antonio Blakeney told ESPN.com’s Reggie Rankin, "I was very comfortable with the coaching staff," after pledging to attend the University of Louisville.

Two weeks later, he told Rankin, “I made a quick and emotional decision based on the wrong reasons," after decommitting from the Cardinal, before following up with a tweet that read, "I am still really considering Louisville. I like everything about there (sic) program, coaches and fans!!"

Which, to those who parent the odd beast known as teenagers, sounds about right. Teens are as certain about their futures as they are the inner workings of nuclear physics.

The difference is, Blakeney is not your typical teen. He is the No. 14-rated player in the 2015 ESPN 100, and what should be his private, independent decision has ramifications from his home base in Florida throughout basketball offices across the country.

Decommitment is not even a word -- shows up underlined in red every time you type it. Yet it is very much a thing in college sports circles, where kids can and do renege on their verbal pledges.

The problem isn’t nearly as bad in hoops as it is in football. Sports Illustrated’s Luke Winn did a numbers crunch study this summer and found that, in 2013, only 11.8 percent of the basketball players he studied made multiple commitments, down from 12.4 in 2012.

Still, it happens. And when it does, it sends coaches into a tizzy.
