20. Marcus Spears, DE, Dallas Cowboys
Spears had an impressive career at LSU, earning First-Team All-SEC honors twice and being a consensus All-American his senior season. He also accumulated six sacks and 49 tackles when the Tigers won the national championship in 2003.
Of course, he was only the second defensive end the Cowboys drafted in 2005, as they picked up DeMarcus Ware earlier in the 1st Round. Dallas hoped that Ware and Spears would become an unstoppable pass-rushing tandem. But Spears was often hindered by injuries and never became a star. For much of his eight seasons with the Cowboys and one year with the Ravens, he was a complementary player. He now makes regular appearances as a commentator on the SEC Network.
