can you be athletic but at the same time not quick or fast?!

Yea look at Shaq. He's not really quick but it's hard to find a better athlete them him.

Of course! Some people can be fast like sprinters, others slower but better for endurance running and such. It has to do with the predominant type of muscle they have. There are two different types of muscle tissue: the fast twitch muscle and the slow twitch muscle.
