To me a super team is largely made up of 3 stars that all do the same thing and try to make it work. I’m not really making an argument for Lavine but Fox, Sabonis, Keegan and Lavine all get their points and shots in a different way so there isn’t the redundancy. You can still fill that 5th starter with a defensive role player. Historically championship teams have a top 5 player, which we don’t have. How do we overcome that? I don’t know that I have the answer, I’m just unconvinced two defensive role players added to our current team gets it done. Now if Keegan goes 2 levels higher that’s a different conversation.
I don't know how we decide who is or is not a "top 5 player". I think if we were to poll the forum there may be as many as 15 different players in the league who fit that category for someone. Fox has slumped a bit of late but for most of this season he was right near or within the top 5 in scoring. He's also at the very least above average for his position defensively and last I checked he was 6th overall in steals per game. Doesn't that make him a top 5 player? Sabonis leads the league in double-doubles and rebounds and lately he's putting up triple double games more often than not. That may not be top 5
exactly if that includes dominant isolation scoring ability, but it's close. Maybe you can win without a true MVP if you have two guys who are in the next tier just below that? Especially if your #3 is a guy like Keegan who is in
Year 2 of his NBA career and has put up a 47 point game and shown evidence of All-Defense potential.
Where I diverge from your team building philosophy is that it appears you want 4 dominant scorers and one defender on the floor for the bulk of the game and I think that works for stats and accolades and good press and All-Star spots but it doesn't work in the playoffs. and it's not a viable long-term strategy for sustained success. We lost that Golden State series in large part because Kevon Looney kicked our butts on the boards. Swap him out for another scorer like Siakam and maybe we even win that series? The role-players aren't just guys who fill in around the edges -- you cannot win with any kind of consistency unless you have multiple role-players on the floor complimenting your stars or your stars are doing lots of role-player things (ie locking people up on defense and hitting catch and shoot threes regularly).
We're not going to take the next step by adding another 20 ppg scorer (just look at Phoenix this season) nor are we going to get there by adding just 1 defender but continuing to play a 3pt chucking lineup in every 4th quarter. It's going to take a team-wide commitment to defense from every guy on the roster and an understanding that more than 3 guys are not going to score in double figures every night. The quickest way to get us there is to add multiple guys who will contribute toward building that culture -- guys who only care about dominating on defense but can hit an occasional jumper iwhen they're left open.
