I wasn't really paying much attention at the time but I thought
I heard Campbell say yesterday when one of the callers said that Robertson would be hard to replace and Campbell said that he wouldn't want to be that guy. The caller then said that he hoped Campbell would get the gig to replace Robertson and I'm pretty sure Campbell said that it wouldn't be him.
However listening to the segment again on the TSN690 website after, to confirm that I had indeed heard him say that, it seems he actually didn't say the "it won't be him" part since it wasn't in the clip when I listened again after.
Although I'm still convinced that he did say it even if I wasn't paying much attention to him at the time but maybe it was edited out before posting to the 690 website after. It's also quite possible that I'm just getting old and losing my mind and have no idea what I'm talking about.
