The Jaguars ostensibly completed their overhaul of their receiving corps by exporting wideout Dennis Northcutt to Detroit in exchange for safety Gerald Alexander. Northcutt, one of Jacksonville’s two high-dollar receiver signings last offseason, had a decent year in ’08 (44 catches, 545 yards), but now he is gone, as are Matt Jones and Reggie Williams. Addition Torry Holt will have to carry the leadership role for the Jags’ wideouts, and youngsters like Mike Walker and ’09 draftees Mike Thomas and Jarett Dillard. In Detroit, Northcutt could be a starter opposite Calvin Johnson if he beats out fellow vets like Ronald Curry, Bryant Johnson, and Keary Colbert and rookie Derrick Williams. Alexander started 16 games in ’07 and the first five in ’08 before getting hurt. But despite being a second-round pick, he was not going to beat out Louis Delmas for a starting role this year. He figures in as a backup/rotation player with upside in Jax.
