DAVIE, Fla. -- Josh McCown is listed as the Miami Dolphins' No. 1 quarterback, for now.
Dolphins coach Tony Sparano was quick to point out that the depth chart is ever-changing, and that second-year man John Beck and rookie Chad Henne haven't been ruled to start at quarterback for Miami's preseason opener against the Tampa Bay Buccaneers on Saturday night.
"I don't make much of it right now. It's something that we had to produce and put out there so we put it out there," Sparano said. "That depth chart in your hands right now won't be the same this afternoon, never mind tomorrow, so it's going to change every single day."
Rookie left tackle Jake Long, the first overall pick of the 2008 NFL Draft, is listed at the No. 1 spot at his position. He is the only rookie currently holding a starting job.
