I couldn't stand Lackey for exactly the reason stated. He'd be getting shelled on his own account, then one of the fielders would make an error and he'd start yelling at them. He always yelled at his fellow players.
I did read how the other players liked him, I have no idea why. In fact he was the player I have disliked the most on the Sox since I've been following.
I lost it watching the 2013 WS when Farrell came to take him out of the game and Lackey wouldn't stop yelling at Farrell.
Strange story....... A buddy of mine ran a bar where Lackey came into for a few nights. He said he was fairly shy around women and had no confidence. One night Lackey kept asking my buddy if he thought a gal at the bar might be interested in him and should he take a chance. My buddy was like "dude, you are a major league pitcher, of course so".
