In the Washington Wizards' latest attempt to get their season headed in the right direction, they will bring a sense of renewal into their home game Sunday against the Los Angeles Lakers. On a four-game losing streak, after it finally started to look like the Wizards had found some sense of normalcy with a 5-2 stretch, Washington tweaked its roster this weekend with the addition of veteran Trevor Ariza from the Phoenix Suns. Headed to the desert are forward Kelly Oubre Jr. and guard Austin Rivers, who was acquired this past offseason from the Los Angeles Clippers for big man Marcin Gortat.
