Attempting to improve our known goalscoring issues by taking a striker from one of the teams that scored fewer goals than us last season would be mental.
(To be fair, somehow we outscored five other sides, but the 5-1 United game put a bit of a sheen on that stat.)
The point stands, though. Main scored 5 in 37 games for a team in fourth place. That's a shite return. He's not going to get more chances to score with us. Obika, to continue @djchapsticks' comparison, scored a healthier 8 in 43, a return Jim wasn't happy with.
I personally doubt it's got any truth to it; he simply doesn't fit our model of how Jim wants to play. Then again, nor does Erwin.
