Apparently the teams that win cups always finish low down the league, oh wait a second. Since we last lifted the FA cup, every team that's one it with a few exceptions have been in the top half of the table. Bang goes that ridiculous argument then.
Your Portsmouth's and Wigan's of this world lifting it are the exception to the rule, not the trend some would have you believe. League position is a more accurate reflection of your likelihood of lifting a cup.
I'd rather be aiming high, than meandering along with the hopes that we get lucky on a cup run. It's like people who work hard, and those who hope they'll trip over a lotto win. Sure we'd all like to win the lottery, but that wouldn't stop us from working hard now would it.
