Your comment was spot-on. Bucks played well, game was there for the taking.
First off, no disrespect to the Celtics. It's a miracle they made the Finals in 1987.
1987 is the year that McHale broke his foot in March. Doctor told him to rest up and get ready for start of next season. Against the advice of his doctor, Kevin played through the injury. In his defense, it may have been that team's last good chance to get to the Finals.
Walton found new life in 1986, was a good bench player that season. In 1987, the injuries re-surfaced. He could only play sparingly, he was close to the finish line.
Celtic bench was pretty thin. Celt starters had to play heavy minutes. Their bench rotation was Jerry Sichting, Sam Vincent, Darren Daye, Fred Roberts, and Greg Kite.
I loved Pressey. Pros/cons of using Pressey as Small Forward:
*Pro: An extra ball-handler. Great in transition. That's where Bucks had an advantage.
*Con: Pressey had guard size. Made the Buck front-line undersized. Parish/McHale killed them on Off Rebounds.
Earlier in the series, Ainge hacked Moncrief near the rim. Moncrief body-slammed Ainge on the baseline, LOL. Ironically, both Ainge/Moncrief got dinged up in 2h of Game 7, had to exit.
Bucks played a good Game 7. John Lucas had a good game, 10 in 1q, 20+ for game. Sikma played well, 34/34 on FT for the series.
Bucks led for almost the whole game. Up 7 after 1q. Bucks got a gift 3-ptr at end of 3q, when Moncrief released after horn but was counted as good. Up 8 with timeout at 7:04 left in 4q.
Pressey got the upper hand on Bird, but he fouled out at the 2:00 mark. Props to Bird, he came through late. Bucks didn't get the transition buckets, and game painfully slipped away.
Celtics' next two series would be dramatic. "Steal by Bird, underneath to DJ" in Game 5 vs the Pistons. And then Magic's baby-hook in Game 4 at the Garden.
