The core issue with Orlando, IMHO, is that they still don't really have a guy who can create his own shot. Howard's a beast, but he's still limited in terms of his post moves; prove me wrong, but he still seems to get most of his points on dunks. He's not like a Tim Duncan. Hedo and Rashard, they're both very good players but they'd ideally be #2 guys; fundamentally, they're jump shooters. On the Celtics, they'd be filling Ray Allen's role, not Paul Pierce's.
Really, their big three are all guys who would be great #2 guys on a lot of contending teams. They don't have a Kobe, they don't have a LeBron, they don't have a Pierce, they don't have a 'Melo, they don't have a Wade, they don't have a Duncan.
They're a tough team, one of the most improved in the league, but I'd rather be matched up against a team that relies on jumpers and can't really rebound that a team like Cleveland.
