Welcome to Bulletin Board Material, the Miami Herald’s weekday roundup covering everything in the South Florida sports scene. A lot to discuss. Let’s get right to it.

Heat in trouble

The Miami Heat’s back is against the wall. That happens when a team drops both home games in a playoff series.

So how can the Heat overcome its 3-1 deficit to the Philadelphia 76ers and advance to the Eastern Conference semifinals?

The simple answer: Win the final three games.

The slightly less simple answer: Show up in the fourth quarter.

The final 12 minutes have been Miami’s downfall and Philadelphia’s greatest strength four games into the series. Overall, Philadelphia has outscored the Heat by 42 points in the fourth quarter in the series, the widest margin of any of the eight playoff series heading into Sunday.

Saturday’s 106-102 Philadelphia win at AmericanAirlines Arenawas no exception. Despite the Heat getting 25 points off the bench from Dwyane Wade (including 12 in the fourth quarter) and forcing the Sixers to turn the ball over a staggering 27 times, the Heat still fell short. The dagger: a 19-2 Philadelphia run that started in the final minute of the third quarter and extended well into the fourth. Miami never recovered from there.

Now it’s onto Game 5. The ball is back in Philadelphia’s court (literally and figuratively), with tipoff set for 8 p.m.Tuesday at the Wells Fargo Center.
