When you describe passion at any age, passion is derived from everything, from the people you work with to enjoying the last years.
At Boston University, I motivated negatively, and I found that although it can work at first, by the end of the year everyone is dying for the year to end and you have lost them. The last two years at BU, I motivated positively and got much better results.
Francisco Garcia could have been a high draft choice last year, probably in the 20s. He's the best wing player I've ever coached. But he's done it the right way. He knew he had to work on his body to become a good pro. When he goes into the pros, he'll be physically ready.
I think they'll come back because they should. One more year and they'll be ready for the next level.
