http://www.chron.com/disp/story.mpl/sports/4861696.html In an effort to add a veteran wide receiver, the Texans will visit with Keenan McCardell at Reliant Stadium today. McCardell, 37, is entering his 17th season in the NFL. He spent the past three seasons with the San Diego Chargers after stops in Tampa Bay, Jacksonville, Cleveland and Washington. He has recorded five 1,000-yard receiving seasons, with his most recent coming in 2003. McCardell, 6-1 and 191 pounds, started 11 games last season and finished with 36 receptions for 437 yards. He had 70 receptions for 917 yards in 2005. 37? Did anyone even want Jerry Rice at that age?
