That practice line is overrated and overstated. I've never heard anyone in the NFL whine about losing practice time because a team didn't make the playoffs. Have you ever heard a basketball coach mention practice as a benefit for making the NCAAT. Or have you ever head Bill Self say "there goes our extra practice time" after another disappointing early exit? It's usually coach speak from football guys whose team has no business being in postseason play.
Basketball and football are a bit different when it comes to practice/coaching. And you can't compare it to the NFL. College practices time is limited by NCAA rules. In the NFL, they can practice as much as they want.
