My question would be, why would OBJ want to go to Buffalo and play in the snow and not be around the Hollywood atmosphere? Working for the coach he seems to really Love, crashing McVays wedding for example, people do not do that to people they don't truly have strong relationships with. I believe this is where he loves to be, playing for a team like the Rams will result in much more money opportunities off the field in LA than in Buffalo. Would not make sense if it's not money related.
According to overthecap.com the Bills only have 5.5M left in space. Rams have 8.1M
