the top 50 tacklers, at a quick glance on last years stats seems to be all mids. a coincidence perhaps? 
would you not think you have more chance of winning a clearance or tackling if you are were the ball starts? 
in regards to being the third best tackler in the 2nd worst team in the afl; 
deledio is played forward
houli is played back
martin is lazy
 b ellis is soft
lambert first year player, also played forward
mcintosh is a kid
edwards, i dunno what his excuse is 
hunt is fairly rubbish
newman is rubbish
big fish, small pond
