I forget. Does one season make a turn around? Though I really like what I'm seeing, consistently in the hunt for a SB will be my definition of a turn around.
That being said, I think it is impossible to really know unless you get to pick the brain of our owner, players, and coaches. Would Stan make the same moves if he knew he was going to play in a stadium where he wouldn't have control over revenue streams? Did the glitz and glamour of LA draw in a young rising star of a coach in McVay? Did the same lure some of our FAs? How many FAs have we lost because of the horrendous CA income tax? Would a guy like Donald rather play closer to home and therefore cost more to sign in LA? I get the feeling he would as he trains at home.
All in all I'd say it was a money move and in order to max money, you gotta win. That will be the biggest push toward a turn around rather than any geographical concerns.
