Just looking back on last season.
Chris Samba: appearences-36, goals-4, assists-1, fouls commited-45, yellows-3, red-1
Phil Jagielka: appearences-36, goals-1, assists-0, fouls commited-17, yellows-3, reds-0
Not great stats to compare especialy for CB's but with the exception of fouls commited where Jagielka is much less rash i would say they are pretty even.
Did you just use games played, Yellow cards, Red cards to compare CBs.? Really Jacko?
