WHY HAS THE OVER/UNDER IN THE GEORGIA BULLDOG vs.WASHINGTON HUSKIES basketball game GONE TO 145 POINTS?????

MY local opened the over/under at 134 points... scoresandoddss.com has the game opening at 138.5 points ...AND, ITHE TOTAL IS NOW 145 with my local....Also, 66% is on the OVER.....even though why is this total so volatile?.... and what's the correct decision? go with the movement and bet the OVER???? OR, GO IN THE REVERSE; BET THE UNDER BECAUSE THE UPWARD MOVEMENT IS OVERVALUED????

PLEASE THE DISCUSSION IS OPEN...
