Bryant Knox previews the Portland Trail Blazers March 16 matchup against the Detroit Pistons. Portland has played both up and down to its competition this season. Detroit enters the Rose Garden as the coldest team in the league, which means the Blazers need to assert themselves as the alpha dogs early in the contest. The key matchup falls at the point guard position where Damian Lillard will take on either Brandon Knight or Jose Calderon. Lillard was outplayed by Knight last time around, but the Pistons’ floor general is doubtful with an ankle injury.
