i get thing started, here a few guys that jumped around:

Stewart Bogart (SMS)- went 103 freshmen, 119 so, 135 jr to 140 his sr year. Stewart lifted his butt off to get as big as he did from a scrawny 103lber.

Chris Hultine (Lawrence High)-103 freshmen, 119 so, 135 jr and leaped to 152 his senior yr.

Brad Sullivan (STA)- i think his jr yr he was like 171lbs and then dropped to 145lbs his sr yr! talk about being different.

Matt VanDealen (SMW)- Here is another that went the other way. Went from 275 his jr yr to a lean and mean 189lbs his sr yr.
