Raynoch Thompson was 185 when he arrived at Tennessee. Eric Westmoreland and Eddie Moore were both about 195 lb high school tailbacks.
Current weight for a high school linebacker is one of the most overblown and overated statistics out there.
The hard thing is determining where they're going to end up at that size. Some guys never put on the 20-30 lbs that is necessary to play LB at this level. Some end up better suited for safety or defensive back.
