text: There are plenty of good D-linemen in high school that are around 200 lbs. The question you need to ask yourself is how quick are you compared to the other linebackers as that will be important. The next is do you play better up or down (3 or 4pt stance or standing up). Being 6'3" if you dont play very well getting your pads down then RB can take advantage of you tackling too high. If that is the case then getting down in a stance (i.e. playing on the line) would be a much better option. And of course the biggest question is how does your coach perceive you, better at LB or DE. He will decide your best position and if you dont want to play that position you need to be prepared and have put in the work at the postion skills you want to play so the coach will at least give you a look there. And remember...do what is best for the team, winning is more important than personal glory.\n  Good Luck!
