The Jaguars begin their summer ticket-selling drive today with a multimedia campaign based on the slogan, "Let's Do This." The campaign includes newspaper and billboard ads and two 30-second television spots that will air for five weeks on local over-the-air and cable channels. The ads will feature several Jaguars players, including running backs Maurice Drew and Fred Taylor, Pro Bowl cornerback Rashean Mathis and first-round draft pick Reggie Nelson, among others.
