I'm 5'11, 180 pounds, never played football, wants to play wide receiver in D3 college. Any tips? can i do it?

I run a 4.5 40 yard dash, don't lift much, but in good shape. Still have one year until try-outs so i can work until then. Plan on getting speed down to 4.5 by time tryouts start. Will never playing before be a major factor. Please hlp.
