Isn't the issue that they're basically no longer a SF team? If so, does anyone really expect San Jose residents to invest much emotion in a team that was never identified with them? It is literally 42 miles from a random SF neighborhood I selected - Noe Valley - to the stadium. That is really freaking far to drive for a football game. Granted, most fans live in the burbs, but it's never really about the getting there - it's about the getting home on a Sunday night, and driving back into SF at 5 pm on a Sunday totally sucks. Unless Silicon Valley adopts the team - very doubtful, in my opinion, given the demographics (East Asians and South Asians constitute the largest demographic bloc in SV now) - the stadium is going to have a lot of empty seats any time they're merely decent or worse.
