There's a sliver of hope yet. Clearly, the connector from the new building, over the canal, and into the IPF, will take place at the point of the IPF expansion.
So we KNOW that East Greentree will get shorter.
The western Greentree field will remain the same.
Therefore, the operative question will be whether the field inside the track could be utilized for football occasionally (when practices are not inside and/or two full 100 yard outdoor fields are required).
In all honesty, if part of the (expanded) IM Field area needs to be claimed by Athletics, I would rather it be a newly constructed softball field.
