Not a big fan of his, but he is a shoe in for Top 10, and has a shot at Top 5 depending on how the rest of his career turns out.
To be quite honest, I think I may put him Top 5. I would be hard pressed to find 5 other guys that have stayed on top for as long as he has.
Probert and Brown immediately come to mind.
He has been at, or near the top for a long time now. It will be hard to over look that.
