Is it to late to start playing aussie rules footy?

im 15 and a half, and am interested in playing footy for a club next season. Ive never played club before, just in grade 6 for primary school. Have alot of pion for the game and support it. I was just wondering if it would be too late to start playing 1st year of colts. Obviously i dont have ambitions to become an afl player...but i have goals to at least play and be a respectable player. Is it too late?
