The first 2 deals make sense, and I think are realistic.
The 3rd one makes some sense, and I think it is the type of deal Orlando would do...but I think it would blow up in their face, since they would be giving up so much shooting, which they need around Howard.
The last deal doesn't work for Indy though. If they are giving up Granger, they need to get more back than Marion's slowly decaying carcass (OK, he's not that bad, but he is clearly on the decline) and Haywood's terrible contract.
