Are we certain that Les didn't take the 49ers job?

Sounds like it:

The new 49ers coach said at his introductory press conference:

"It’s a perfect, competitive opportunity for me and the rest of the San Francisco organization to be part of a team, a team that has a chance to win with the San Francisco 49ers. I’m excited to meet the players. I can’t wait to be around those guys. Those professionals, those strong men, those leaders and start building a team. I have unshakeable confidence and a great faith in the human agency and human beings in their desire to be part of a team"
