You look very good, from the one picture provided. Lean, definitely have some muscle, but you need to get a LOT bigger. As people have said, 6' 4" is both a blessing and a curse - you really need to put on a lot of size in order to be competitive, but once you fill out you will look big and impressive. I would say most top guys at that height compete at a weight of like 265-285 though so you have a lot of weight to gain.
My advice would be to hold off on the steroids longer than the winter - you've played a sport that involved so much running for so long, and as you said yourself, you don;t even really have your food sorted out completely. Before you spend the money on drugs, spend it on making sure you have TONS of healthy food, and make sure you are meticulous about eating plenty.
That, in combination with just good old hard, heavy lifting in the gym without all the running, will probably result in great gains for at least a year or two. If you're serious about bodybuilding, the drugs are inevitable but you seem like a young guy, you don't need to rush into that until you have built a REALLY solid foundation without them.
Bauber, for example, is a good 5 inches shorter than you, and in his RMP thread he puts up pics of him at 20-25 lbs heavier than you before he started using. So you have quite a bit of size you can put on naturally.
Also, if you put up more pics we will be able to tell you more. Nobody cares if your legs look sad when youve just had a bad injury, but it would be good to see them anyway, along with back, front, maybe some poses.
