Ok, I will take the word extreme out, I may have been a bit harsh. But having watched most of the games Jackson has played in, when running in a straight line against a defender he is slow. When he has the ball at his feet he is good as he has quick feet. Comparing him to Deuchar, Peaso and Savo for pace is just comparing new degree's of slowness. If we take Sammy out the equation, we have no one that can run onto a ball (goal against rangers) at pace. This is off course my opinion.
Jackson is a great player and can hold the ball up as well as Sammy, but I think we need a bit of pace upfront in the SPL.
