West Texas A&M is building an on campus stadium that could be expanding over 22,000 seats as capacity. I think they are aiming for FBS. I think their football program was put on probation for giving benefits like FCOAs to their players in football. Same with Arkansas Tech as well. There are several D2 schools looking at giving extra money on their scholarships for the hard cases of players like what is going on at the D1 level. It is still against the rules to give FCOAs to players of any sports in D2. This is a problem with D2 schools who have sports in D1 right now. Some of the D2 schools that have hockey at D1 are contemplating if they should go ahead and do a FCOAS for hockey, or move their whole programs up to D1.

Now as for FCS schools if they want to go Independent at FBS level? There are several who could get games going.

Big SKY:
Eastern Washington
Sacramento State
Cal-Davis
Cal-Poly
Portland State
Weber State
Northern Arizona
Montana
Montana State

Big South/ASun:
Coastal Carolina
Kennesaw State
North Alabama (added that they could get games with FBS schools since they were the last D2 schools that beat a FBS team)

CAA:
Towson
William & Mary
Villanova
Richmond
New Hampshire
Maine
James Madison
Albany
Stony Brook

MEAC:
South Carolina State
Bethune-Cookman
Florida A&M
Norfolk State
Savannah State

MVFC:
Northern Iowa
North Dakota
North Dakota State
South Dakota
South Dakota State
Missouri State
Southern Illinois
Western Illinois
Illinois State
Indiana State
Youngstown State

NEC:
? Maybe a Central Connecticut State?

OVC:
Eastern Kentucky
Jacksonville State
Tennessee State
Tenn.-Martin
Tenn. Tech
Eastern Illinois

Patriot:
Fordham
Lehigh
Lafayette
Bucknell
Holy Cross

Pioneer:
Jacksonville?
Dayton? Large student body and alumni which they could easily slip in as an FBS candidate if they do major fundraiser.

Southern:
Everybody

Southland:
everybody

SWAC:
Southern
Jackson State
Alabama State (rumored that they wanted to join the SBC)
Grambling State


These are the schools that played FBS schools a lot.

Future consideration?
West Texas A&M which would bring back a rivalry to New Mexico State, New Mexico, and UTEP and maybe Texas Tech. Very long history at D1 level.
North Florida could start up football. They were on the short list of Benson's as an expansion candidate.
Wisconsin-Milwaukee could actually help attract people to go back to Wisconsin as factory jobs are returning. Wisconsin needs another school in the FBS to keep people in state.
Another Minnesota schools. I think Mankato State could be hands down as the bigger name to move up.
Long Beach State hinted MWC, but they can't join unless they restart football.
Wichita State no need for saying.
Azusa Pacific is growing private college that could reach D1 soon like California Baptist and Grand Canyon.
Colorado Mesa could be interesting case. Their metro is larger than some FBS schools who are smaller. Colorado Mesa > Washington State's Metro.
Colorado State-Pueblo is in another very large city in Colorado.
Omaha, yes Omaha. We do need another Nebraska school in FBS which could help Nebraska residents to stay in state.
Canada schools. Simon Fraser, Calgary or British Columbia can help bring FBS football into that country. Imagine when they hold a bowl game in Canada between one of the Canada schools and a MAC team?

Remember, these schools could do a deal with the conferences already in FBS like play 5 games a year, and have a bowl tie in with that conference. Sun Belt could give the same deal with football to the schools in their footprint which includes Lamar, Missouri State, Central Arkansas, Jackson State, Jacksonville State, Alabama State, North Alabama, Kennesaw State, Chattanooga, and so forth.

PAC 12 could offer Boise State, San Diego State, Hawaii, and New Mexico a 5 game conference tie in without adding them for all sports. That could open 4 spots up in MWC for other schools. Big 12 could do the same with BYU, Colorado State, Houston, Memphis, Cincinnati and East Carolina.
