re: What's at the root of the problem between Nick and Lane?

There is no contention between them at all. Nick is a little jealous of Lane's ability to dial up plays as nick knows that he's only good in college bc he can spend more money to recruit than anyone else. Play calling isn't nicks greatest skill and he knows it. Lane , on the other hand, has shown that he can outcoach nick head to head. I think that may be the only tension there, but I don't think it's eating at nick as bad since Lane helped him hide his poor quarterback evaluations recently
