If DW ends up talking to the coaching staff maybe he should say a few words about Melker too.
Seriously though, I agree with all of what you have said here. From what I have seen over the last few years of PDB, when things are not working he reverts back to things that have worked in the past. From trying Pavs-Jumbo for too long, sticking with Melker on the 4th line, running Vlasic-Braun, etc. Neither of these are working but they have in the past so they are 'proven'.
EK65 is a new variable in the equation and PDB has not utilized him correctly. The fact that EK65 has not played his best so far, has not helped the situation either because that basically makes PDB revert back to the known quantity again. My concern is exactly that, PDB's inability to make adjustments to the system as the players we have on our roster are getting better and faster. He is sticking to the same system/style that worked 3 years back with an entirely different set of players. Back then we had no EK65, Ryan. Meier and Labanc were just pups getting started. No Sorenson either.
This is a completely different team from 3 years back and yet, the system is still the same.
