What a load of toshIn part, it's a bit silly sometimes for Port and Collingwood to "hate" each other when realistically they have similarities. Both hated by rivals in their states. Port against the rest in SA and Collingwood is the rest in Vic. Both ARE Magpies and both ARE black & white yet slightly different designs and different meanings within their historic jumpers.
Whilst both will be against each other in the field, funny enough both, you'd imagine would be in part, "allies" due to their similarities.
I dare say there'd be a lot of Port supporters who barrack for Collingwood 2nd and vise versa. I actually believe Eddie McGuire has that same feeling, respect and what not for Port but won't actually say it. As to why he refuses Port to wear their traditional jumper, we'll that's because he's selfish too.
