Welcome to the forum. Unlike a lot of your fellow Stokies, you seem a reasonable enough bloke - even if wrong on this matter.
I'd like to ask you a question: Had Shawcross got to the ball before Ramsey, where was he intending on putting it? I ask because the force at which he made his attempted tackle was so strong that in the above scenerio, the ball would most likely have cleared the stadium!!!
Also, I'm not certain that Ramsey is absolving Shawcross of all blame:
We all know that it was a 'have some of that!!!' type challenge and unfortunately the recklessness and force with which Shawcross went into the tackle made it almost inevitable that the recipient of it would end up getting hurt - unfortunately in this case, very badly.
The point is, there wasn't any urgent need to make the challenge - other than a mixture of anger at losing control of the ball and a misguided determination to let the other bloke 'know you're there'. The consequence of that attitude is a young player suffering pain, spending a long time out, and running the risk of maybe never ever returning at the same quality level - as we are sadly seeing currently with regards Eduardo.
Now can you honestly tell me those acts of machismo were worth it?
