Why didn't the Raiders go to Las Vegas immediately?

“I’m shocked that they didn’t go the route that the Rams went, to leave St. Louis and come to [Los Angeles] and play in the college stadium, even though it can be a pro stadium, until their stadium is built.

I love the route that the Chargers took, because they’re going to play in a 30,000-seat venue in Carson [California], it’s a soccer stadium, for a couple years, whatever it takes.

And I can’t figure out why Al Davis’ son, the man in question here, didn’t just say ‘hey, we’ll go on to Las Vegas right now and we’ll play in UNLV’s stadium.’ It holds 42,000, they have a college bowl game every year. Why not just go do that?

Why not avoid the agony that you’re going to put these Raider fans though for the next maybe three years it’s going to take to build that stadium in Las Vegas?”
