Last season, we were all fairly happy with Mulgrew and Edwards - both fairly solid in defence and both chipped in with a few goals. This season though, they are both shaky in defence and I can't think of either of them scoring a single goal for us. How can it be so different from one season to the next? How do two players go from good to honkin in such a short space of time? Is this the Siegrist/Birighitti effect?
