NBA middles/shenaningans ?

[MCP313]

I love when I see these during the NBA regular season when I look at the finals every night and I already have seen quite a few.

No clue what to think since I obviously didnt watch these games but I still find it very amusing.

Boston opens 3.5 closes 6, wins by 4

Mavs open 2.5, close 7.5, win by 5

Rockets open 2.5, close 6, win by 3

Jazz open 2, close 6, win by 4

Boston o/u open 187, close 194 lands 188

A couple obviously had a few big discrepancies which didnt get middled but is there any other sport that gets middled as much ? Pro gamblers have a field day in this league or what ? Coincidence ? Personally I think shady shit still happens in this league. Still I find it very amusing when these games get middled.
