OR and WA already know the Big 12 will take them at anytime. Under what circumstance would the Big 12 say no to either? As long as they do not insist on dragging along WSU and OSU, they know they already have an open invitation. What the Big 12 needs is to keep the PAC exodus going...such as with the AZ schools and maybe CO and UT. Things become much more challenging for OR and WA when they are facing a conference of 6 or 8 instead of 10.
