In the end, do I agree with him singing the song, and it being okay? No. Do I approve of it? No. It reeks of this kid not being a leader, IMO. And Tennessee needs, and should want leaders.
I just have a feeling that this is one of those situations that is going to work itself out. See Drae Bowles. See Joc Bruce. TA either wilts like a daisy in spring practice under the pressure, ridicule, and possible punishment, or he owns it and emerges stronger and better for it. Perhaps even learning the consequences of not being a leader when he should have, and developing those skills to be one in the future as a result.
Pruitt doesn't need to kick him off the team. He just needs to allow him to go thru hell this spring and see how he emerges. Tennessee will be fine either way.
