Let's keep in mind that some people say or communicate outrageous things just to get reactions. Sammy has plenty of money and doesn't have to conform, so he can tweet whatever comes to mind as long as it's not political....Williams Hayes believes in Mermaids and that dinosaurs never existed, my son who is now a Software Engineer once believed in Santa Clause (sorry for those who still believe) & the Easter Bunny, sometimes things are communicated just to gain attention.
Now I do believe Watkins might struggle to learn a playbook or maybe just is used to be successful with his God Given ability and just does not want to put in the time. That could change later in his career or it might not, however, regardless of Scientific Facts I have learned throughout my years never to be shocked and to at times ignore some outrageous comments or communications from Athletes, Movie Stars and Politicians after the 22nd of November of 63.
