Examples are important and RJ is a clear example of a guy coming in that is a "non-key" guy to start the season that becomes a key player. If they don't add Batum or Jackson we win that series no sweat. I don't know that before the season you would look at the clippers roster and say "Batum and RJ are key guys to where this team ends up in the post season". Which is likely to be the case if we brought Dunn in. I'm more irked that I give an example and you do "well actually that's not a good example" and it clearly is... then we go to "well examples don't matter". Okay.
You just don't like Dunn which is fine. You maybe should just start with I don't like Dunn... but its weird to go "meh" on Dunn while singing the praises of Kyle Anderson... you know they are approximately the same type of shooters right? Going from Bogey to Anderson is a huge, huge downgrade in shooting that will be felt for sure. If Mike and Don are so bad on defense will it really matter that he gets 30 minutes while Dunn would only get 15 maybe? If Quin is not going to play non-shooters like Dunn 15 minutes a game to spell Joe/Mike/Royce/DM... is he really gonna be excited about Anderson's iffy shooting in his "key" lineups. Dunn and Anderson are different defenders for sure but they both do similar things we need help with.
The money matters but if Ryan is presented with a sure opportunity to piss $7-8M down the drain with Hughes or place a $20M bet with a much higher potential to get an on court return then he might be persuaded.
I still don't think it's a great example, especially because he already played a role for them the year prior. The main difference I see is that as a player, I believe RJ is more established than Dunn. So even if there wasn't PT for him (there was), I think of them as different players. If we had kept Niang and brought in Gay, it doesn't change my belief that Niang is a rotation player. My opinion of Niang is completely independent of whether or not we have Rudy Gay...but his minutes are not. Likewise my opinion of RJ is independent of whether they brought in Kennard or not.
I've also never had this "we have enough" attitude that you seem to have a problem with. I've acknowledged that it's probably tough from a money standpoint, but I do not care about the money. I have said that I don't like Dunn so many times. I don't know how many times I have to repeat it, but I guess I have to do it more : ) I get the appeal. I really wanted him last year. But with his injury, seeing how defense is evolving, and tight roster spot situation....I've gotten lower on him.
Independent of money I'd rather give the spot to a younger guy and put in one more lottery ticket to find the next Mann. That's why I'd personally pass on Dunn. It's not because we have enough, it's not because of the money, it's because I have more belief in the young players. The roster spot really comes down to Oni/Brantley (I actually think Brantley > Oni), but I will admit that my optimism on Butler/Forrest is also a factor here. I want to see them get time. I know you didn't want to block Doke from minutes, that's a factor for me here too. I don't see Dunn as a true alternative to JC where they would actually be competing for minutes. I think he would only get minutes if there was injury...and if that comes around I'd want to see Butler/Forrest get that chance.
I'm very high on Anderson and don't see him in the same tier as Dunn. They aren't close as shooters and definitely not as total offensive players. I'd be a little skeptical of Anderson's shooting as well, it is a big drop off from Bogey. Shooting is so important and that's why I was high on a certain backup PF lol. But Anderson is still a good offensive players in the other areas. He's a great passer, good ball handler, solid around the basket, great in the mid range. I honestly think he had one of the most underrated seasons in the league last year and I think he could get even better playing around our spacing.
