Tuesday night’s 95-90 loss to Milwaukee was the Mavericks’ second straight at home, piggybacking Sunday’s 103-99 defeat to the Lakers. It also was a lousy way to conclude a stretch of eight games in which Dallas had seven home games. The Mavericks went 5-3. Not nearly good enough. Now they go on the road for seven of their next eight games, starting with a Wednesday night game at Memphis. “It’s not looking good, for sure,” said Dirk Nowitzki, whose 21-point, 20-rebound performance Tuesday was wasted. “Obviously this league is crazy and in my period in the league I’ve seen a lot, but this is definitely getting tight. “If we want to make a push, we’ve got to find a way to win those close games. And if we can’t pull it out at home, what’s the confidence level on the road?” In addition to the four-point loss to the Lakers and five-point defeat to Milwaukee, the Mavericks lost a four-pointer at home to Atlanta just before the All-Star break. Dallas is now 16-12 at home and 9-19 on the road. “Not good enough in this situation, simple as that,” Nowitzki said of this just completed home stretch. “Me missing so much time and then coming back, not being 100 percent, we were so far behind the 8-ball. We knew coming out of the All-Star break that we’ve got to win almost every game. “It was a lot to obviously expect from this team, but we’ve just got to win these close home games. We can’t be talking about the playoffs if we can’t beat these East Coast teams at home, like Atlanta, and this one hurts us. We’ve got to find a way to win close games at home, simple as that, if we want to be a playoff team.” At least one Mavericks voice attempted to exude optimism, although coach Rick Carlisle’s words and tone sounded more like gallows humor.
