How is length of time relevant? They have the proof of concept. It worked for them, it works for us now.
I would submit they are the exception that proves the rule. It was a one-off, and those two aren't like Dame/Ant other than in size. Thomas had maybe the tightest handle in NBA history (Kyrie is up there as well), and Dumars was a 1st team All-Defense player. Neither of Dame or Ant is either of those. I fear we could be back to a slightly better version of Dame/CJ. Two guards who take the bulk of the shots while the rest of the team has to play defense.
Dame has averages right at 20 shots per game for the last 7 seasons. That seems unlikely to change all of a sudden and it probably shouldn't. He's earned that and proved to be worthy of that amount of attempts.
In Ant's last 23 games where he has exploded, he is averaging 18+ shots per game. That is 38 shots per game between the two of them, and very similar to what Dame/CJ have done for years....which rendered us going no where in the Playoffs.
In the last 10 games, the Blazers are averaging 89.6 FGA's per game. And that is with Chauncey's emphasis on pushing the ball....which Dame very rarely does. Either Dame and Ant are going to have to have decreases in the amount of shots they get per game, or we are going to be back to 2 players taking 42% of the shots and everyone else dividing up crumbs and covering on defense. The problem is, you don't really want Dame taking less shots and Ant is shooting at an efficiency level since he became the lead guard that is off the charts....so you don't really want to take shots away from him either.
That leaves 51 shots for the remaining 6-7 players. Nurk wants his touches, as he is getting 13+ shots per game in his last 24. If he is going to remain at that level (and stay happy and productive) that now leaves 38 shots for Hart, Winslow, Nas, Grant?, McLemore?, and Watford. That is an average of 6 shots per game per player. Since coming to Portland, Hart is getting a VERY efficient 13+ shots per game. Grant is averaging 16 shots per game in his last 2 seasons.
Someone is going to have to take the hit. Unless they are winning at a high level, that can cause problems just like it did before. And does Dame suddenly after 10 seasons, start sprinting up and down the court? When CJ blew up and joined Dame in the backcourt, there were those who were dubious from the start and it completely proved out to be an ineffective style in contributing to being a contender. Not enough size or defense, and then asking teammates to cover for them when they were taking a large bulk of the shots.
Ant is a bit different than CJ, but combined with Dame, this seems eerily too similar. Hope I'm wrong, or Dame's career will continue to be one of being on a nice little team that isn't a threat to anyone of contender status.
