From what I've seen D looks like this
Schaefer/Sauder
Henry/Mccall-Ambrosio
Daviault/Mccall-Ambrosio
D'ellesio/Holomego 7th
I think it comes down to how offensive or defensive Mccall plays. If he's all offensive, he can't play with Daviault who tends to play very offensively at the expense of d coverage. I like the way D'ellesio has been playing, but they have been using him mostly against opposing 3rd and 4th lines. Holomego is a defensive d, but I'm not sure what's going on there sometimes. I'm also concerned if Erliden gets injured from overuse, but that has been said by pretty much everyone.
It is also tough with Henry, the kid has the build of a stay at home defender BUT when he gets open ice is insanely fast and can rush with the best of them. I personally like his game and appreciate he's not 1 dimensional in his defending style.
Holomego, agree. The guy is stay at home for sure. I will applaud him for his shot blocking. He does tend to eat up a lot of shots in front of the goaltender, but thats about it. For his size he's not very strong. He's not very fast. There is almost 0 offensive upside there either.
Ambrosio and D'Alessio definitely seem to have a solid upside and shouldn't be rushed this season. We've also added Willis who appears to be on the "smaller" side at 6' and 160. I am anxious to see him play. While Knight was playing I love the fluidity in his skating, but he also needs time to develop.
I don't think we need another puck moving defender, but rather a stay at home one who can play 3rd line and has time to grow.
We should be just fine with Schaefer, Sauder, Henry and a +1 to eat up most of the top minutes.
