Knighta would've played 300 if that mongrel Frawley didn't make him retire
Knights would have struggled to get 21 odd more games out of himself.
He probably could have done it, but all the same, he was a shadow of his former self in his last couple of years and it would have been embarassing to see him crawl over the line. Better he left with his dignity in tact having been a great contributor.
It's even embarassing seeing Campbell run on the spot nowdays. It's good that he's calling it quits at year's end. Not a moment too soon.
