My understanding is that the field is the size the magicJack requested. Be interesting to see if this makes the magicJack adjust.
As far as building a soccer stadium, the idea was that the magicJack would play this year at FAU's current field, then if all went well they would discuss helping to build something like a 5,000 seat stadium on FAU's campus.
For what it's worth, FAU people seem pleased by the attendance so far...
