It is TOOOOO easy to sell tickets! I looked at Ticketmaster's site and was blown away at what's available from Ticket Exchange for the Rams / Bucs game. And that is just Ticketmaster!
Back in 2000, I TRIED to get tickets for the Rams / Bucs MNF game. There was almost NOTHING available. The very few that were out there were $400+.
Call it Free Enterprise or whatever you want but, IMO, the sale of one's tickets through a phone is not good for football.
