Does anyone really have anything against Nantz? He is great. I can see complaining about Romo, but not Nantz. Not when there are so many that are so much worse than him. He has an iconic voice. Plus, he has great respect for Josh Allen as a person and a player. I'd take Nantz over almost anyone.
But yes, Romo has gone sour. I liked him the first couple of years, but he has really gotten bad.
