I don't think championships should be dispositive, but tournament runs do speak to performance against stronger competition than is seen in most conferences. Certainly that's the case for EDD, IMO. Which is why Larry Bird taking Indiana State to the finals vs Magic Johnson would be counted more than EDD getting Delaware to the S16. I, for one, am not going back and recalculating opponent RPI for the years individual players were at their schools, but I think there's a general sense that the candidates from the bigger conferences will have an edge over players from mid-majors, and that UConn's OOC plus tourney runs puts them in the top tier despite playing in the AAC.
I agree with your no brainer list of Griner, Wilson, Stewie, and Maya with the caveat that bballnut's post that started this thread specifically eliminated Maya
Perhaps there should be some discussion about whether this is appropriate: in addition to Moore, the 3 season requirement takes out any player who went the JUCO route. I don't know if Danielle Adams would qualify as all-decade anyway, but I'm not a fan of eliminating her based on years played vs impact.
I think Ionescu is first team and should be a no-brainer, but obviously others disagree. Of the PGs being disussed, Sabrina, Diggins, and MoJeff all won the Lieberman twice. I believe Sabrina is the only one of those to have a NPOY on top of that, and assuming she's the favorite for this year she could joint Sue Bird as the only player to get 3 Liebermans. MoJeff gets a bump over Diggins for the 2016 DPOY.
This also leads to the question of whether the all-decade teams have to be composed by position like actual teams or like some of post-season honors teams. In other words, do we need a post, 2 forwards, and 2 guards on each team? If so (and following bballnut's ruling on Maya):
1st team
Griner - C
Wilson - PF
Stewart - SF
Ionescu - SG
Jefferson - PG
Still thinking about my 2nd team and HM, but just want to add that I'm surprised that Victoria Vivians isn't mentioned more by the Miss State fans.
