With new OBS can we really have a trainwreck anymore??

[DaveASA/FED]

OK, I guess I have seen too many OBS calls and discussions about them here lately. It made me think about OBS and Interference and train wrecks, can we really still have a trainwreck anymore?? My classic trainwreck is at 1st base, where the ball, runner and fielder all get there at the same time and collide. Now with the new OBS rule why wouldn't that be OBS? Fielder was going after a thrown ball, but if the fielder didn't have possession of the ball and the runner was obstructed running then why would this not be OBS?
