I don't know how reliable those "global ratings" are but according to them Monk is 2nd at the moment in the 6th man of the year race. According to bookies though Westbrook is unlikely to win it (he is 8th favorite with 35 odds, Portis even lower with 100) even his teammate Powell has lower odds, as the 3rd favorite.
The favorite is Tim Hardaway Jr with Monk being second and Clarkson, Levert, Bogie and Mathurin after them.
