Well, the voice actor in that cartoon is not too fast, it may be little bit fast for learners, but for Turks it can be followed easily. And that actor has no accent or dialect at all.

It is nothing to do with  " dev ağız ". You can even tell from the context, I mean that cartoon character is talking about the game [american football..or some game], so it is about defence in the game. 

its quite clear. And if you are talking about television shows, it depends on the show , I mean, try to watch TRT ones. Since TRT is supposed to use standart Turkish.

And even if there is an accent or dialects in a tv show, won´t be big problem for them to be understood by any Turk.
