It's pretty simple for me, if I'm Dino, I sit Taj down right now (no sense in waiting):
"Taj, you're a heckuva ball player. However, you're either one of the family or you're not, you decide. Openly calling out your teammates during games will simply not be accepted moving forward and you will be kicked out of the program if it happens again. Consider this your warning. Put in the extra work over the winter/spring/summer like TJ and others do with Tommy and the other QBs. Go the extra mile. No one owes you anything. You need to redirect your frustrations into being a leader in the WR room, not a detractor. We are only as good as our weakest link, both on and off the field. I love having you around, but things need to change."
