Heat coach Erik Spoelstra has been asked this question all season. When responding, he always gives the same answer: "I think we have enough."
Spoelstra should quit thinking and just say the Heat has enough. The question has resurfaced because Miami has lost four straight games. Never mind the Heat won 21 of the previous 22. This is the Heat, where every stretch of the season is analyzed like college football by fans and media. A few midseason losses won't keep the Heat from playing in a major bowl.
So Miami has hit a few bumps recently. It happens. Just ask the Mavericks, Celtics...
