What position would I play in rugby?

I'd say a little underweight for your height for forwards but your height would be an advantage at lock if you are balanced by someone of equal stature.

If you have good speed and agility- I'd also look at learning the back game from wing position.. you'll have to really run though!

Try a few out- its not like football where everyone is a specialist. Every position needs to be able to ruck and maul, tackle, attack and defend- just some do it more than others!

At 6'7" the instant and obvious answer is lock. Your height is wasted in any other position.

That said you will need to bulk up a little bit -- put on another 15 to 20 lbs of muscle. Time to hit the weight room -- and in particular the squat rack. And remember -- rugby isn't American football. You don't get to stop for a breather after every tackle. Cardio fitness is critical.

lock. your height and weight will contribute largely in the forwards. (line outs, scrummaging). perhaps centre also maybe, depending on your attacking and defending abilities. talk it over with a coach show him what you can do and take his advice in positioning. good luck
