If the goal is to make big NFL bucks over the longest period possible, the NPV differential of 1-2 years more college isn't very meaningful. Perhaps if your family REALLY needs the money, a 1-2 year difference is a relevant consideration. Dont see this high need NOW for money being an issue with the Murray family. To conclude, ego, not 1-2 year competition concerns, would be the primary driver motivating a switch. Of course, a late switch following a 7-month commitment would bring up other long-term negative impacts, but that's a story for another thread on another day.
