Its not like Ammon Olson or Billy Green became stars this year after having left BYU. Heaps neither. Really 95% of the kids who get a football scholie were stars on their HS team but the jump to college is big, the competition much more athletically comparable, the work ethic needed more stringent. I'm not of the opinion it is a developmental issue at BYU any more than other places really.
Geez if it were a development issue we'd be laughing at Nick Sabans inability to develop NFL qbs.
