From your weight I'd guess you're a kid. So you'll be fine at 6' 2" to play lock. The lifters will enjoy throeing someone under 100 lbs up in the air.
You don't need to be tall to be a lock being tall helps but it's not necessarily as long as your good in the line-outs and scrums have a massive appetite for work.
That is about perfect height for this position
yes you are tall enough to play lock I am 6'4 and play lock weigh more then you do but it is all about your technique, and how you bind with the rest of the scrum. so pretty much just practice....practice..practice and you will get better
Absolutely my dad was around the same height and weight and played lock. Just work on your technique and create a strong bond with your other lock and you will knock back those other lanky players.
that's fine as long as u are strong enough to play the position
