The question is, just how hard did the Raptors poke the bear?

We find out Sunday afternoon.

The upstart Raptors gave the mighty Miami Heat all they could handle late last month in south Florida, succumbing only in overtime in a game that was far closer than anyone — and that includes the Heat players, one presumes — expected.

Fresh off a spanking administered to them in Indiana on Friday, the Heat arrive at the Air Canada Centre, and Toronto coach Dwane Casey implores his team to expect the best Miami has to offer.

"No, we're not okay," Casey said after practice at the Air Canada Centre on Saturday. "And I hope they understand that we can't think we're going into this thinking we're okay. They're going to come in a different team, understanding that the game down there went to overtime. They're going to come in with that edge, their high beams on and we have to do the same thing."

But how intense are those Miami "high beams" that Casey was referring to?

The Heat hardly are on a roll of late but neither are they suffering from some kind of mid-season doldrums or some flaw in the construction of the roster.
