If we extend that concept to other areas, then ASU and UA should be football powerhouses now, as AZ is one the fastest growing areas in the country.
LA/SoCal in general will always be one of the most highly recruited areas in the country, simply based on the population base.
If you look at the rosters of other teams Oregon, Washington, ASU, Utah, Colorado, those teams all have many players from LA.
One of the main draws is: If you come to (you name the place) you will be a starter. If you stay in socal, you may not be.
It's all cyclical. Teams will have a few good years, it may be 3-4 or 7-8 years, then they will fade, only to be back again with a new combo of coaches and players.
Agree...but asu and ua did have a lot of success in about 1995 to 2005....i agree with the cyclical idea...but as long as their are newer cleaner safer environments to build there will be lots of migration there and 10 to 20 years later...one can see strong programs develop. I remember when ua and asu were considered podunk schools....remember when florida colleges had just a few good football schools...now ucf is barking.....ucf? However a great coach will always upset the trend.
