Sure, the Heat's starting line up is pretty good. Beyond them, they have almost nothing of value though. Wade's health is crucial. If he is fully healthy and playing well then they could be a challenge.
Just to have a visual, these are what I imagine the match ups would be in a series:
Kyrie ---- Dragic
Shump --- Wade
LBJ -------- Deng
Love ------- Bosh
Moz -------- Whiteside
Seems pretty evenly matched. Yet once those 6th, and seventh men start entering the game then our advantage really becomes obvious. Bringing TT, Smith, and Delly off the bench is a nice luxury. Not to mention we still have Marion, and Miller to step in in case injuries occur. The Heat have nothing of that caliber.
Maybe I'm unknowingly wearing the wine colored glasses but I still like our chances against Miami. We're deeper, and more talented in my opinion.
It feels nice to be able to say it again, but we still have Lebron James in a playoff series.
