UCLA has never had an very good place to practice football. We used to play at the Coliseum across the street from USC, and now play at the Rose Bowl nearly 20 miles away in Pasadena.
There is a great Track and Field facility - but the center is used for field training, not for football. We practice on a field built over the roadway and it isn't great.
But Pauley Pavilion was redone this year, and they took the time to redo the practice fields as well (they are right next to Pauley). Apparently they leveled it all, and rebuilt the fields, one with grass and one with astroturf.
