I think Walton is great. He's funny, and he knows the game. He also calls the game pretty well for both sides, without going too far for the home team. He played before my time, but I still find his jokes funny and can relate to him.
Even though he represents my team, it can be tough listening to Tommy sometimes because he's just TOO biased, like the Cs never commit a foul lol. Plus, a lot of his "humor" is a little too old school for me.
Still, those 2 plus Clyde Frazier are all pretty entertaining to me.
