Bush is off to a hot start mainly due to the injury to McAllister, but McAllister is back as of today and as expected, Bush's workload and hence his value decreased today. Bush still has value, especially in PPR (point per reception) leagues, but he's definitely not in the same class as AD. AD is off to a slow start, but I would hang onto him - there's a good reason he's the consensus #2 overall pick in almost every draft and he will put up the numbers eventually - don't panic and unload him. Coles doesn't really add a lot of value to the package as he's not that highly ranked.
If ya want a bunch of opinons, ya may wanna post this in the Draft, Trade forum - nothing wrong with asking for help here but there's a lot more traffic over there!
