I'll bite
Not sure what they've proven?
1) Their only racing two days a week and that proves nothing, except their on life-support.
2) It's the only mile track in the East (beyond Lexington).
3) M1 has taken horses away from Freehold (was already bleeding) by writing lesser condition races because the wagering base at M1 cannot compete with the racino-purses (Hawthorne, Maywood and Balmoral did (early 90's) the same thing by copying race conditions (NWXPMCalimers) and taking horses away from Fairmount (promoting Fairmount's demise, and eventually their own).
4) The major stables stay in close proximity because of the major stakes held at M1.
IMO, the only thing M1 has proven is that ten (10)-horse fields offer better pools and wagering interest (even though M1 has difficulty maintaining ten-horse fields in the overnights), and that was already known (for decades).
Freehold races more days than M1 (for far lesser purses and stakes), and yet the handle at Freehold is more substantial than many racino tracks.
Why KILL Freehold?
With all that said, it's a gallant effort to save The Meadowlands, and that perspective of the sport.
NY, Ohio, PA and Ind are all racing five days a week. Course their racinos.
