He went on to play at Northwest College but transferred the next year to Butler Community College, where he earned All-Jayhawk Conference honors, after registering 42 tackles and 6 sacks, helping his team win the National Junior College Championship. As a junior, he transferred to Mississippi State University where he was a reserve defensive tackle, recording 28 tackles, 6 quarterback pressures, and one sack.

He received second-team All-SEC honors and was also a semifinalist for the Outland Trophy.
Blade was selected by the Dallas Cowboys in the third round of the 2001 NFL Draft, after dropping because he was seen as a talented, but underachieving player. The team had finished last in the NFL in run defense the previous year and took a chance on him. After missing the first three practices of training camp in a contract dispute, he dislocated his right wrist and sustained ligament damage during his second full practice. The injury forced the team to place him on the injured reserve list. The next season, he came into training camp out of shape and was still hampered by his right wrist injury, so the team decided to release him on September 1, 2002.

Blade recovered from a preseason MCL sprained and would go on to play a key role in the NFL first ranked defensive unit, starting 14 games at left defensive tackle opposite La'Roi Glover, while registering 18 tackles, one sack and 8 quarterback pressures. The Cowboys expected him to keep improving, but the next season he relapsed into his old habits, reporting to training camp overweight and was released on July 26, 2004.
