It's really not one of the worst comparisons. You're either very young or just ignorant.
Boyd is a three time best and fairest, one of those won in a team comfortably superior than Cotchin-era Richmond. He is also a dual AA.
Looking at Boyd's second AA year, 2011, against Cotchin's 2012 (unfortunately the extended stats are not available for Boyd's 2009 when he won a best and fairest in a team that narrowly missed the grand final) and Boyd won more of the ball, won more contested possessions and won more clearances. Comfortably too. So much for Boyd not getting his own ball.
The Cotchin v Boyd comparison is apt. Cotchin is overhyped, especially by Richmond supporters.
