There's no reason why one cannot surpass someone else's state of badness.
However, you've already made your statement he's the worst player ever. This is an absolute statement and anything else you add to this can only be to illustrate and emphasise the point, so simply re-stating the same thing with a different verb won't really add much.
What you're looking for is extra color - you've drawn the black and white outline, but there are many ways to color it in. eg. give examples of how really bad things can be...and he is badder!
he's the worst player ever... like...even worse than hitting your thumb with a hammer in a wet salt mine.
