MormonRasta, I believe you are wrong about the gap not closing, and I will show you why. I do agree that in comparison the BCS money is less than compared to ticket sales and merchandising, but it is still dramatic. This is the scenario I came up with, there are several suppositions, but I believe it's fair for a generic example.
First, I tried to take a middle of the pack BCS team with a stadium attendance of 60,000 compared to a Non-BCS of 30,000. I also assumed that a BCS team would play 7 games at home, whereas a Non-BCS would only get 6.
I doubt my table will show up nicely, so here it is spelled out.
BCS Team
60,000 seats x $20.00/ticket = $1,200,000/per game - 20% share with other team (-$240,000) = $960,000 x 7 home games = $6,720,000 + 500,000 (A conservative amount from away game ticket sales) + BCS Revenue Sharing 2,000,000 = Grand Total: $10,660,000
Non-BCS Team
30,000 seats x $20.00/ticket = $600,000/per game - 20% share with other team (-$120,000) = 480,000 x 6 home games = $2,880,000 + 480,000 (A conservative amount from away game ticket sales) + BCS Revenue Sharing ($176,470) = $4,136,470
so, lets assume that the NCAA finally grows a backbone and steps in and institutes a playoff system and levels the playing field with equal money sharing, and forcing a 6 home and 6 away games (just imagine).
BCS Team with Playoff
60,000 seats x $20.00/ticket = $1,200,000/per game - 20% share with other team (-$240,000) = $960,000 x 6 home games = $5,760,000 + 600,000 (A conservative amount from away game ticket sales) + BCS Revenue Sharing 2,000,000 = Grand Total: $9,560,000
Non-BCS Team with Playoff
30,000 seats x $20.00/ticket = $600,000/per game - 20% share with other team (-$120,000) = 480,000 x 6 home games = $2,880,000 + 480,000 (A conservative amount from away game ticket sales) + BCS Revenue Sharing ($2,000,000) = $5,960,000
As you can see, the gap went from $6,523,530 a year to $3,600,000. Thats basically cut the gap in half.
