Lots of reasons why the Rays don't draw well, but the MO of their front office plays a role IMO. Casual fans buy tickets, and those fans like having consistent stars to root for. A team that wins 87 games a year on a low payroll by churning through players to win the $/WAR championship is probably going to draw worse than a team that wins 87 games a year and keeps their stars around, all else being equal.
