well... we've pretty much done that for a while. we do not really have a #1D man. Our depth isn't as good. we have pending UFAs with high AAV who have time and time again not shown up in the post season when it really matters. On top of that we have goalies who have performed decently but are still unproven in the playoffs.
Eventually one has to take calculated risks instead of going all in all the time. My preference is to wait out this year and see how the same core plays with a new coach. If its still the same old same old then there are most certainly significant changes needed.
My personal preference is not to add too much at the TDL.
Sort of feel the same but nonproven goalies isn't a deal killer, Murray, Binnington and Dryden are my references.
Bad d is also not a deal killer, I think of Pittsburgh and their first Cup in 2016, they didn't have a single name defender, their defense looked dreadful on paper.
The only time TO was lucky enough to go all in for the playoffs and that player was healthy was when TO acquired O'Rielly, the only time TO made it outside of the 1st round.
TO needs better forwards, we saw TO basically getting dominated by Chicago and a wounded Boston for 2 periods, of late, that tells me that TO needs a humongous upgrade at forward or a true #1 d-man. TO won both games but we know that TO's current forward group doesn't have enough to win in the playoffs. Every year during the playoffs TO's defensive record is good enough to win but getting timely goals has proven impossible.
Being dominated by Chicago and Boston is a strong indication of TO's probable future in these playoffs, heart/character is something that should be on display in at least 2/3rds of games against such weak opposition and that TO can't muster that is extremely telling.
TO has bunch of depth forwards, trading for a Laughton would simply be another depth player and giving away anything other than a low draft choice would be silly/stupid.
