Dude, work on your skating any chance you can. As others mentioned, you may be a stud on the football field but you will be owned by smaller guys if you decide to be the tough guy. I've been on the receiving end and delivering end and it is a reality check (got knocked on my ass by a 5'8" dude and I leveled a 6'6" 300lb guy that thought he was going to take a run at me). Given your size, work on your balance and screen the goalie, until you feel comfortable skating and making plays. I wish you the best.
