Here's my opinion on all of them:
HOH Hall of Fame - Why? We already have a hall of fame. Are we going to induct Lindros a few years early? Are we going to skip on Phil Housley? Are we going to induct 1-2 long forgotten players? In the end, the hall of fame is mostly fine aside from a few small points, and I don't think this will give us any worthwhile list at the end, nothing that differs too much from the actual hall of fame.
Best Players by Birth Year - To me, this is more trivia, than a list actually worth something. It can also easily be conducted by a set of polls in the polls section (or even here) without needing an actual "project". Majority of birth years ranking are quite....straightforward.
Best Duos of all-time - To me this is impossible.
@BenchBrawl came up with a good list of suggestions as to what qualifies as duos in a previous thread, but it's such insanely subjective that i'm sure everyone will have their own criteria of what duos qualify. No one will ever agree who the duos are, which is a deal breaker at the start. Also - length of duo vs peak, what counts more?
Best Pre-Consolidation Players - This is 100% a worthwhile project, no question. If you guy run this, i'll follow and learn, but I have very little knowledge to contribute here, so won't vote for it. Also - I think this will be very hard, and I wonder how much participation will happen. If you guys go this route - I'd suggest trying to get a commitment from a minimum number of posters to participate actively, or it'll fizzle out.
Most worthy future HHOF Inductions - A bit similar to my thoughts on the first one, why? Also - are there even any names worth discussing outside of maybe ~10-15 who aren't active players where we'd need to do a ton of projections? "Is Matthews/Eichel a future HHOF'er" - doesn't seem very project worthy. And if we're spending a ton of time debating whether Alfredsson or Zetterberg are worthy of HHOF - well, they are fine players but on the very low end of HHOF worthiness, so it isn't all that interesting.
Best WHA players of all-time. Like he pre-consolidation list, this is a fine worthwhile project (pre-consolidation is moreso) - I don't know enough about the league so don't know that i'd be able to participate, but I would enjoy following. Not sure it's the best of projects to undertake though.
Best dynasties of all-time - This could be ok, but there's only....a handful of dynasties, right? So are we only ranking ~5-10 teams? If so - let's do this in a week and move on? Maybe I'm missing something.
Which leaves me with my top 3. In order from least to most favorite:
3.
Best Teams of all time. This could be fun, and different than anything we've ever done. Would also be a worthwhile project, as ranking top teams isn't something you come across often. I think the only way this project makes any sense though is if we spend a lot of time ahead of time coming up with the right criteria of team, vs everyone doing their own thing. Would need a lot of discussion. The 2019 Lightning is a fantastic team, one of the best ever - but they got swept in round 1. Are we ranking best teams 'on paper' or on performance, playoffs too or just regular season? Also - if you ignore the sweep - Tampa vs rest of league is a giant last year, but Tampa vs other all-time teams in a non cap era....is way lower on totem pole - which is the measure we're ranking by? Habs won 4 straight in the 70s - do we rank that as "1 team" or rank each year as a different team, and if so...it gets redundant? I think it's important these types of issues get discussed and agreed upon at beginning so everyone isn't voting based on separate criteria, rendering the actual list just a jumble and not representative of much.
2.
Next Best Players of All-Time. This would be fantastic. I've never seen any worthy all-time list go farther than 100, so this would be a very valuable project. Instead of comparing Gretzky to Lemieux to Orr we get to rank Sundin vs Oates vs Luongo - the type of players you don't normally get to rank.
This is also time sensitive - it makes sense to do this after the top 100. If we wait too long- in another 2-3 years, we'd probably have to redo the whole top 100 vs just start off as #101, since opinions/posters will change and it wouldn't be representative.
1.
Best Single Seasons of All-Time. This is my personal favorite - peak seasons. I think we'd have to do
one season per player max - because we don't want to have the project rank 25 of Orr/Lemieux/Gretzky seasons before getting to anyone else. We'd also have to decide how to include playoffs if at all. Personally - I say no playoffs, as it throws things off. Fedorov in 1994 is amazing and could rank very high- but it's the year Detroit happens to choke in round 1 - so does that mean we now rank Fedorov's "peak season" lower because of a bad team result? Not even representative of Fedorov as a playoff performer, because if you took any of his 97 or 98 playoff run, they'd hold up very nicely with 1994.
So - I would say best single season regular season only of players, and 1 only per player - that's my suggestion. I also think this would be a very worthwhile list - as it's not something that's ever been done before in a serious way, and would cause us to look at many players in a different light, focusing on just their very best season.
