Almost 10,000 yards later, running back Clinton Portis is calling it quits.
Portis is just 77 yards shy of the 10K-mark for his career, but after nine years in the NFL Portis officially announced his retirement on Thursday.
Portis was one of the best running backs in the league for a good amount of that time, and when he entered the NFL, he had two explosive years. During that time, he had more than 3,000 yards rushing, 29 touchdowns and averaged 5.5 yards a carry.
The former Denver Broncos and Washington Redskins running back took to his Twitter account today a couple of hours before his press conference.
After all this time, how does Portis look on cards (Get a full Portis checklist here)?
Total cards: 3,997
Total value: $38,873.21
Average value: $9.73
That Rookie Card number is right. Portis has 65 of them ranging in value from a $1 or $2 to $40.
His 2002 Sweet Spot RC autograph numbered to 125 has a high book value of $40.
