I hate to say it but Tyler needs to go to the league. There's nothing else for him to prove to NBA scouts. He probably won't get drafted but he'll make a roster. All he really can do is regress next season. It's Fox's turn at the wheel and I think it's better for him and Tyler if they don't play together. It would probably end up hindering both of them.
I'll say this about Tyler, he's probably the best all-around PG I've seen at UK in some time. He's the best PG Cal's had at UK. He's a better shooter and defender than Wall was. I wish Tyler nothing but the best when and if he decides to leave but hopefully the rest of his teammates can step up and help him make a run this year.
