Heat made great moves - but they got older.

Last year they had veterans ( Iguodala, Ariza, etc. ) who had championship experience and that resulted in a 1st round exit.

This year they add 2 championship experienced vets ( Tucker / Lowry ) -- could the result be similar?

While yes they have improved defensively -- offense and the bench is the question : Tyler Herro has been wildly inconsistent as is the rest of the bench.

Ultimately, good additions -- Applaud the Heat / Pat Riley for constantly pushing the envelope.

I think they're putting themselves in the best position to win a championship based on what they can do so you can't fault them for the moves. Championship or not, they're definitely better than what they were.
