Have heard this too. They're all over Carlisle early days with the Doggies as the main rivals. Have cooled a little as it became likely that Henderson would re-sign. Will know more after the Blues sign up a new coach.
I will say this - I get the feeling that there won't be a ton of trades involving KPP players this uear. There are a few in FA (Henderson, Kruezer, Carlisle, Hawkins, Dixon) and not a lot of teams who require such players - enough to offer enough money to pry players away.
This is off the back of KPP players being traded (Boyd, Bruce, Waite, Ryder, Jacksh) last trade period and so many first round draft picks being KPP.
