Hanging on the rim is considered bad form except in the case when it is to prevent a player landing directly on the other guy. Metu had no choice but to protect himself AND JV by hanging on the rim until the area under the basket is clear. If JV was concerned about being disrespected maybe don't get dunked on in the first place, but once you do, get out of the way and allow the player to get his feet down safely. JV is a punk pure and simple and should get an indefinite suspension that ends 2-3 games after Metu returns to play. Of course the league would never do this, but 5-10 games seems completely appropriate.
