I take exception to some of your analysis.
Brantford:
The Bulldogs sold Donovan. He may very well be the top D-Man in the League, at least the top 19 year old anyway. HB in Kitchener may have something to say about being the top D-Man overall. That is a huge sell off piece for them. That is 25-30 minutes per game of stellar contribution wiped right off the board. they also traded Van Vleit who is another key D-Man for that team. They added Sobovilev, so that is a nice replacement piece but still doesn’t come close to helping replace the two guys they traded away.
Kingston:
Kingston added Dubois. Nice little piece for sure. He will help then at both ends of the ice Which is what they need. That move improves them. How much? Not sure how much one individual piece helps but they will battle for sure.
Oshawa:
They added Punnett. IMO, he was the top OA D-Man available. He will help them for sure. They will battle as well.
Ottawa:
I will simply point to what Sirius said. Not only do we add the two capable centres that will give us additional offence but sliding the wingers back to the wing and giving others a more capable centre will also add to the offence for those players. So, for Ottawa, this is not just adding the offence from the centres, but also at least a 50% increase added to 2 of the wingers. It is like adding three key forwards. Mayer, if nothing else, will stabilize the top 4 and ensure that we don’t have incapable D-Men playing above their station. He will also be the PP#1 guy that we have needed. He, alone, will add 5% at least to our PP.
Peterborough:
They will struggle to win games. Period. They are now the weakest team in the conference. They will not make the playoffs. The question really is whether they will slip below Niagara who has a considerably better roster right now. I think the Petes will end up in last place in the league. I think their under-over for points is 46 to finish the year.
In light of all that, I think Brantford has pushed themselves out of the race as of today. Oshawa and Kingston have marginally improved. Ottawa has dramatically improved. You have to consider Ottawa the front runner for the division as of this morning. The deadline is later today so that landscape could change. I don’t see it changing too much though.
