he could have had an off game. Either (or both) of them could have felt the need (or been told to) drop deeper because of the threat of MV wingers. Or any number of different things.
It's quite hard to tell on TV, but can't really recall many instances where i was screaming at manny to give wee Mac the ball, and he gave it to someone else or missed the pass.
I'm guessing you were at the game though Valeo? So it may have been easier for you to see what runs he made off the ball.
