My fear is that Rosscoe can be slow on the turn or off the mark. When ya are steaming forward ya gather pace, strength and momentum. That is Rosscoe's absolute strength - nothing better than seeing the big man in full stride - he is more of an attack minded player. Defending wise his first time tackling and positional sense help him out and how many times have ya seen him appear to be struggling and get there (just) in the end. That is because he is really good at tracking back inside and taking in the angles - You just cannot afford to do that at centreback - the angles are limited.. Fast forwards are always on yer feet, looking to turn ya and get in behind. And Granty would not be able to cover that - he is also a true centreback and not of the "sweeper" nature. Now Caff is a defence minded player. He is pacy and aware, of a "sweeper" nature and a foil fer Munro. If he could develop his distribution then he would be a much improved player.
