I can understand where the oddsmaker is coming from when he made this total. Boston College beat Miami, 84-62, at home on Jan. 12. So 146 points were scored in that game. The Eagles, though, went crazy in that matchup sinking 18 of 35 shots from beyond the arc for 51.4 percent 3-point shooting. 
Boston College's season 3-point shooting percentage is 33.7. Since that game, the Eagles are averaging 66.2 points in their last five games if you discount their matchup against Notre Dame two games ago. The Eagles rank 263rd in field goal shooting.
Miami is averaging 64.2 points in its last five games. The Hurricanes are a well below average offensive team. They rank 307th out of 340 Division I teams in scoring, 284th in field goal percentage and 329th in 3-point percentage.
