6'2" and 210 is almost ideal for a Senior H.S. LB/FB...get him in the program, after his first couple of seasons you are going to have a 6'2" 230-240 LBS. LB/FB on your hands, pretty good size for a MLB. Also, the whole speed will come with size, its hard to judge a high school kid, and when coming from a small school even harder because they are playing 2-3 sports a year, and not getting to live in the weightroom like they would at the FCS level, the weightroom and training will develop the speed and size. Also, having the "nose for the ball/instincts" will help a LB overcome being a little slower. Just my thoughts....
