Yes, Boise State gets several very good Texas HS players (and other NATIONAL signees) each year because of what they've done getting to Access Bowls. In addition to the ENORMOUS PRESTIGE they've also garnered their conference $18M+ each time they've gone to these games.
Just as in baseball and basketball, Louisiana Tech beating LSU would just be seen as "yeah, LSU had a down year. Its not like Tech will do that again in the next 100 years".
A single win over LSU would be nice, but we need to think bigger than that if we want to thrive in FBS football and adequately fund our athletics programs.
