If you're a tested athlete you need to stay away from test-e and other long ester based steroids. Anavar, Primo, Winny, Tren-a, test-p and test-suspension are going to be the best bet if you're tested...of course even then those can be a problem if the test is random and you don't know when it's coming.
That said, if you really know what you're doing then sure, you can get away with using long ester based gear that carries long detection times. Deca is actually a fantastic steroid and a perfect steroid for any football player, it is an absolute favorite of many NFL players. It will by no means slow you down, that's just ridiculous.
