Design looks clean and smooth but what does the 4444 in your name stands for? There's going to be much confusions with the name. A lot of typographic errors from people typing 444 instead of 4444 and typing Sports in place of Sport. Did you give thoughts to all that before choosing your name?
I'm asking because traffic leakages is a big deal in any online business, that's why people invest a lot of money to acquire fine names that has little or no ambiguities.
I think this 4444 stands for nothing but op or owner of the site tried to take a domain called sport but it is not available then tried 4sport again not available, then 44sport that is also unavailable then 444sport that is unavailable too finally tried 4444sport and got that. I searched before replying you on godaddy and noticed like this.
We tried to come up with a name that is easy for users to remember and that is unique.
We have chosen for 4444sport, since its 4 times the 4 in the name.
As for me, the name is very easy to remember and that's okay. However, there is a danger that scammers will try to make phishing attemts as it is easy to get confused by typing 4 three times instead of four. Maybe you should somehow gently warn your users and advise them to be careful.
