I think its harsh on Crooks to suggest dropping him. In the 3 league games before Sunderland, he set up a goal against Blackburn, scored 2 and an assist against Birmingham and played very well against Millwall. He wasnt taken off against the Mackems because he was particularly poor either, it was just tactical.
I don't think he played particularly well against any of them.
He certainly didn't in the first half against Blackburn or Birmingham, he just popped up with goal involvements in the second half which obviously ensured he kept his place.
He's not a striker, and I think it's daft that we're using him as one whilst having 3 strikers on the bench or outside of the 18 and 1 playing out wide instead.
He's great as a goalscoring midfielder and he's certainly an option from the bench for his presence, but he's not great in the air, he lacks pace and he's not amazing at holding the ball up.
He's also spent almost his entire career as a midfielder.
