Raghib "Rocket" Ismael: 5'11', 187 lbs, 4.28 seconds 40 time......SPEED!
Raghib "Rocket" Ismael had an 80 receptions, 1,100 yards receiving and 6 TDs season for the Cowboys in 1999 when Troy Aikman was throwing to him. Rocket's speed definitely was a difference maker.

Too bad the Cowboys got Rocket Ismail to play for them towards the Rocket's last few years of his career. Imagine if the Cowboys had drafted Rocket Ismail in 1993 when he first joined the NFL? Wow, Rocket could have easily helped the Dallas Cowboys his rookie 1993 year and every year after that when the Cowboys won the Super Bowl in 1993, 1994 and 1996. Heck, Rocket with his speed could have made a difference and helped reach and win a Super Bowl in 1995 when the Cowboys lost in the NFC Championship Game to the 49ers. Just think about that. SPEED KILLS and definitely makes a difference.
As for Antonio Bryant, he never had speed. For a WR, he ran a slow 4.57 second 40 yard dash, and it showed on the field the few years he played in Dallas.
As for Alexander Wright and his alleged 4.14 seconds 40 time and winning the NFL's Fastest Man Competition in 1992 and 1993, the man was a track star, not a bonafied football player, hence why he struggled to ever accomplish anything with the Cowboys or any other team thereafter.

Alexander Wright even stunk as a player in college (Auburn). Absolutely was not a football player. Only good for running track.
