Being around 10 years now I have a few mulligans that stand out. In the long run you win some you lose some but heres a few highlights.
My first ever trade in Capwise was 10 years ago in my first league the ECFL. At the time I was just getting interested in prospects and had the biggest man crush on Peter Mueller thinking he was the next big thing. Traded away Ryan Johansen for him straight up. Three years later Johansen puts up 70 points at the same time Mueller now in the Swis league is playing for Kloten HC. Mueller to his credit it has been lighting up the Czech and Austria
