Portland has allowed at least 110 points in each game. … The Trail Blazers controlled the first half in Friday’s game against the Los Angeles Clippers before ultimately falling 119-103. … Tiago Splitter is leading Portland as interim coach after Chauncey Billups was arrested earlier this fall in a gambling scandal. … Jerami Grant (Achilles) will miss his fifth consecutive game for the Trail Bla
