I got cut off so here goes:
I really don't see them going into 4 markets just yet, but well maybe they can in a neo-hub style. I've posted about this for a while on XFL Board and ArenaFan already
Philly is the logical choice up north due to its presense along the NJ border were it can effectively pull some fans from that Market. Granted the NJ teams is targeting North NJ/NY area- but beggars can't be choosers.
The Subaru Park is just o/s of philadelphia city which avoid all those related regs and costs. It's home to Philadelphia Unon MLS Soccer - they may not go for 20 games but... Even if Philly/NJ/Mich/Pitt played a round robin style 4 weeks there - the league could squeeze in 6-8 games in say weeks 4-7.
NJ at Philly
Pitt at Philly & Mich at NJ
Mich at Philly & Pitt at NJ
Philly at NJ
(6 games)
All other games back in Birm.
But you could add like so:
NJ at Philly
Pitt at Philly & Mich at NJ
Mich at Philly & Pitt at NJ
Philly at NJ & Mich at Pitt
NJ at Mich and Philly at Pitt
NJ at Pitt and Philly at Mich
(9 games - 4 philly in market, 4 NJ near market)
All other games back in Birm. And that only leaves one Mich/Pitt game played in Philly.
Something along those lines.
Also NOLA - can do a XFL-esq practice in place (Birm), but play in NO w/o flying as Birm to NO is busing distance.
They could add 5-9 games that way (playing Birm in NOLA is net no gain).
Conclusion: The USFL can go from 10 in market games to as few as 21 or as many as 26 using a low cost partial northern hub and NOLA game day only strategy. That covers 65% of the games providing TV with a better audience while more importantly building fan bases in 4 local markets. That's my 4th&long USFL Yr 2 strategy.
