The FSC division has had a 24 team playoff since 1978, and is partially the inspiration for the 12 team playoff in the FBS this season.
FCS figured out over time that they needed a playoff schedule of home game matchups until moving to a neutral field at least the semifinals and championship game.
Quite frankly a lot of FCS teams/universities lost hundreds of thousands of dollars travelling on the road within the playoffs and refused to partake financially to accept a playoff bid...
The FCS playoff selection committee learned to use economics to make the playoffs feasible,...they would chose a ranking system somewhat coherent based on the wins and losses record,...but at the same time reward universities who could financially absorb team travel across the country,...another economic assessment was to reward the home game to the team who could produce a greater home attendance,...for instance if Georgia Southern was ranked 10th nationally in the FCS and North Dakota was ranked 2nd, Georgia Southern would get the home game since they had a history of higher home game attendance.
Now traditionally the FCS did not get much TV money and teams had limited budgets,...
But having a 12 team playoff in the FBS on complete neutral fields (in southern cal, Texas, Miami, Atlanta) throughout puts a focus on selecting a playoff team that may either travel well and/or get good tv ratings,...
Having home games for the highest ranked team in the playoff schedule until the championship game removes the "potential" economic factors of selecting teams based on regions and fan base profitability,
A complete neutral field playoff inserts dr pepper and corporate enthusiasm in place of college football pageantry,...
And maybe all 12 FBS teams selected into the playoffs can absorb travel and would never decline invitation because of TV money and being programs with larger budgets,..
but how much integrity do the college selection committee have that they would disregard pressure from selecting a 9-3 notre dame team against a 11-1 Boise State team for the 12th spot in the playoffs?
If the FCS playoff selection committee is a guide, economic forces play a role,
And a pile of neutral site playoff matchups only makes the situation worse
