One thing that annoys me about Pardew!

I don't think it was stupid because it worked. However, I do agree that your suggestion seems a better option.

I no longer hate Perch btw, he's now on trial

Perhaps Pards thought it would be better tio have Ameobi's hight to help win balls and get possetion and control? Would be a poor reason mind as he gives the ball away far to frequently (when he can be bothered to take it in the first place)
