I got rid of a 1D mark three because I felt it was too geared up for sports and wildlife. I got the 5D3 cause I was told it was a good all rounder and with the same AF system as a 1Dx you can't go wrong. Errmm no.
Get shot of your current gear and get a 1D mark IV. Same price as a 5D3 and quicker off the mark. It'll laugh in the face of rainy days and take a few knocks too. Look at the amount of posts from 5D3 owners who say the camera isn't weather proof and also that the AF system might be from the 1Dx but it's certainly not a quick camera. Outdone in response times with at least the 1D markII
Certainly not my experience. I spent 2 games tweaking the AF settings, but once I had the right combination, the AF was lightning fast. I could just be sitting there, and as a player sprints and makes his jump for a dunk, I can pick up the camera, focus and shoot him doing the dunk in 1 sec (that includes my moving the camera into position, then hitting the AF ON). No tracking, etc. Now there might be faster paced randomized action sports beyond NBA players out there that the 5D3 may not be quite up to task, but I don't know what they are. The 5D3 is certainly more than enough for children athletic events, which is what this situation is. The 7D is more than sufficient for that too, so either direction is fine, as called out in the OP, but the 5D3 low light ISO will be much better and out of camera JPGs are better due to the new JPG engine over the 5D2 and 7D.
My history is with 2 1D3s, 1 1D4, a few 7Ds, and now the 5D3. They are all quite close, the 7D at the end of the line though, but the 5D3 is very close to the 1D3/1D4, almost no difference that I can see.
The final championship game of this last season, all with the 5D3. Then again, this is just my opinion on the matter, what do I know beyond what I shoot?
NBA D-League Final Championship
One of my favorite shots due to his expression. He was fun to shoot. This was ISO 20000, which comes in handy in night high school football for example.
