I'm sure others have pointed this out but I haven't participated in the threads here much since the downer of game 7... but replacing McLeod/Foegele with Skinner/Arvidsson could be a 30 goal increase in offense.
The 2 new guys could combine for around 60 goals whereas McLeod/Foegele probably top out at around 30 combined. This assumes healthy seasons for all involved of course.
Defensively I don't think you lose much either overall.
Arvidsson is very good defensively and Skinner is dogcrap defensively so that somewhat evens out.
Foegele was average at best defensively and McLeod at evens I would say was decent but not far above average defensively either.
The fact that you now have a full time Henrique at 3C is a pretty huge upgrade as well.
You've got a young and improving Holloway in the mix as well who has the potential to be just as good as McLeod overall as well and if the playoffs was an indicator... Holloway may ALREADY be as good as McLeod.
They upgraded the forwards very solidly when you have Arvidsson/Skinner in with an improving Holloway and full year of Henrique.
On D... Desharnais out and Stecher in... which is an improvement imo (as long as Stecher recovers from his injury).
Hopefully the improvement keeps coming from Broberg because he looked solid in the playoffs.
Depth pieces added at RD like Carrick and Brown don't hurt either... some depth on RD was definitely needed.
Goaltending is what it is... average at best with Skinner/Pickard in net... and it will likely stay average unless someone jumps out of the blue up to the NHL with an amazing season from Rodrigue/Ungar in the AHL.
Overall based on what Jackson and the Oilers have done so far... I'm going to say an A+ is deserved because forwards are definitely improved... defense has been slightly improved with Broberg improving organically and Stecher (hopefully) healthy for a full season.
Goaltending is same as last year but hopefully Skinner can build on what ended up being a decent playoff performance... and Pickard was surprisingly solid all year including in the playoffs when called upon.
