Think about what he has done in the past week or so.
1. He did not talk about his commitment or when he was going to commit.
2. It becomes public that John Wall and company are going pro then boom like clockwork it comes out that he is going to commit at the BOO Williams Camp (this is a NIKE event). This means he was planning on committing to UK and it was probably a done deal.
3. Brandon KNight said he did not want to be a one and done player. Which means thats he would be around during at-least Teagues first year. This being said Teague changes his commitment date
4. He changed his commitment date because UL is a Adidas school, and it would not have been classy at all and could have cut out future show deals by committing to an Adidas school at a NIKE camp.
This is why there is no longer a question in my mind that Teague will be a Cardinal.
