Plays...

[crazy voyager]

The travell is just stupid, should've been called no question about it.
The first video. Well the OOB play is not good but the lead is to close. I've seen it before and I've been there, if you don't back away in that situation you will miss it. Why nobody else stepped in and called that I do not know though, the trail should've been able to make that call without for example.
The second call (elbow) is also due to an error by the lead. He follows the ball insted of watching the players closest to him. That's an error I think we all make though, it's not good but it will happen.

The blocking foul: I think they could've just dropped that and went with a no call. I do realise why the official calls it though becuse from the second angle it's impossible to say if the contact is legal or if the defender uses his side to initate it. Like I said I think they should just've ignored it and played on.

The last play has to be called, I agree with what has already been posted that even though it's just a small bump it forces the dribbler out of bounds and therefore creates a significant advantage for the fouling player. It's not a call you'd love to make but it has to be made, and that's what we're payed for so I don't think there's much more to say about it.
