As for that last "non-call," meh, it happens.
When a game goes to the wire like that, anything can happen, and invariably half the fans will be pissed.
I do think there is a lot of inconsistency in the reffing. Whether that benefits team A or team B is random.
I thing I have noticed is that refs will call soft fouls early, as they seek to impose order on the game, but once those players get up to 3 or 4 fouls, they go much easier on them.
It also seems to me that they go harder on fouls the further they are from the basket. Players get pinged for soft blocking fouls and inconsequential reaching in outside, but a player under the basket can get absolutely mugged and not draw a foul.
And don't get me started again on the current interpretation on charging. The rule used to be clearly understood. Now it seems the refs are taking the "easy" route and basing it purely on contact, hit the defending player's chest and its called a charge, hit his hip and its a block.
