The Jaguars are currently averaging 63,193 per game. That's 27.3% higher than last year.
The game against the Browns will not be blacked out. The NFL has decided not to make it the local game in Orlando (they have Raiders @ Steelers, no idea why), but it will be available on Sunday Ticket here since it's not blacked out.
Keep things up, and hopefully they'll stop talking about us moving to LA soon. (Which I, personally, do not believe will ever happen, because Wayne Weaver is committed to Jacksonville.)
Speaking of the Raiders, they are dead last in attendance, and were dead last in 2009 as well, over 5,000 per game worse than us that year.
