I prefer field performance to appearance myself. A guy should look like he wants to for his own self [within limits] but not because he's thinking about other people looking at him. That actually is a weakness. [it can even be a team-building weakness if he is using stuff as a "self" featuring effect rather than team].
I remember an old self-featuring defensive back [for the KC Chiefs??] who bragged about himself as "The Hammer", with certain strutting appearance elements for effect. In the championship game the Lombardi Packers zeroed in on him, blasted him several times, and the guy actually lay down and quit. The Packers were laughing on the sidelines, and his teammates were embarrassed.
Is an athlete confident in what he's "bringing" or not?? I know that I and my four brothers just responded to that sort of posturing by getting a little more "dedicated" to sending "posers" to the bench. If a guy is "authentic", OK; usually you can tell the difference pretty quickly. I'm sure that our guys tend to be authentic about these things, or, if not, are growing out of them. So, I'm alright with them choosing their personal "style" as long as it does not detract from focus on the actual job, nor the fact that we are a team.
p.s. that DB fairly quickly retired and went into what his real profession was: acting. [he wasn't great at that either but at least he was in his element.]
p.p.s. By the way, I'm sure that anyone that Coach has offered is a fine young man and is above the egocentrism referred to above. Deontay Greenberry will undoubtedly be a wonderful guy on campus and a great teammate. That's who "we" are.
