Former Vikings offensive coordinator Scott Linehan, who now holds the same job in Miami, announced this week the Dolphins will go to training camp with the starting quarterback job still undecided. Maybe. But if last weekend's mini-camp was any indication, Gus Frerotte has a clear-cut advantage over the scattershot A.J. Feeley. The much-traveled Frerotte, who played in Linehan's offense for two seasons while with the Vikings, is obviously more comfortable. And while he wasn't particularly sharp in the mini-camp sessions we watched, Frerotte doesn't have to be, at least not to hold off Feeley. Fact is, No. 3 quarterback Sage Rosenfels looked better than Feeley, who really had some horrible stretches. You've got to hand it to the Philadelphia Eagles for being able to wrangle a second-round pick out of the Dolphins for Feeley in the spring of 2004. Of all the dubious personnel decisions made by former Miami general manager Rick Spielman Ã¢â‚¬â€œ and there were plenty of them Ã¢â‚¬â€œ surrendering a second-rounder for Feeley might have been the worst of all. Which probably helps explain why the prefix former precedes Spielman's name.
