If you could buy a Coke for a dollar or a Pepsi for five dollars, which would you purchase?

If you were paying 60 dollars a month for internet access, then found a similar plan for 40 a month, would you still pay the 60?

It sounds obvious, but when you look at the payrolls and rosters for the majority of franchises, you see there are still many lessons to be learned.

And some teams, like the Knicks, are about to learn the very hard way.
