Things were a lot different when I was starting out because the bodies available at the time sort of made the decision for me. When the sports bug started nibbling I was shooting a 400D and there were two upgrade options available the 6 fps 50D or the 10 fps 1dmk3. Although not fullframe the APS-H 1Dmk3 couldn't take EF-S lenses so every lens choice was going to be EF because I knew I was going to want the 1Dmk3. These days, with the 7Dmk2, the body is certainly up to the task and sport photographers might be able to get away with EF-S lenses - though I cannot think of a 70-200 f/2.8, one of the goto lenses, equivalent off the top of my head. Personally I'm glad I have both bodies in my bag. The 7D + 70-200 combo gives me an awesome close-game setup (112mm-320mm) that I don't think I'd be able to match with a FF setup unless I switched to Sigma.
Obviously my genre based choices arent the same for everyone. Still, I've got a much broader range available to me with the same set of lenses by choosing to utilise both formats. 16mm on the FF at the wide end up to 640mm with the 400mm on the 7D and that's not including the 1.4 and 2.0x teleconverters.
If you need an ultra-wide on the APS-C bodies you're probably going to have to get yourself a EF-S lens and sell it if you switch to FF but all your other ranges are still pretty much covered by EF lenses.
I observe a lot of photographers shooting with crop sensors in European football m
