Abilene Christian wide receiver and kick returner Johnny Knox is scheduled to visit the Miami Dolphins and the New York Giants next week, according to a league source. Knox, who was clocked between 4.29 and 4.34 seconds in the 40-yard dash at the NFL scouting combine. At the combine, the 6′0, 185-pounder also registered a 10-2 broad jump and a 35-inch vertical leap. Source: ProFootballTalk.com
Knox will be a late second day pick...he could even go undrafted, but his speed from the combine may keep him on the board. He's also got good hands...
Well look at it this way, Ginn will now be a full time receiver, Bess will develope and focus on being a better slot receiver. Outside of those two guys the Dolphins don't have a full time returner. Cobbs is a #3 RB and is constantly used on offense so his focus can't be on returns alone.
