I’ve said it before, but the Lions were very very happy for him to go (coming directly from a 3 time Lions premiership player who still has very close ties to the club, although not an official role). They wanted him gone last year (and he wanted to go), but no club was interested at the asking price. He pulled his head in a bit after that and he was a bit cheaper this year in terms of dollars plus nothing needed to be given up in a trade, which was why it was easier to find a suitor.
It will be very interesting to see how he goes at Port and what effect he has on the team as whole.
I’d say with our policy of picking up players of good character, there is a fair chance guys like Kerr and Looney had some input in what he’s like and that played a part in why we didn’t chase him.
Plus as others have said, maybe he simply didn’t want to come to us.
