Your argument is spoiled by a simple fact: we have 0 chance to land those names.
If they'd been achievable for our firepower, we would have already taken one of them last summer. No way. PG and Boogie are keeping the doors open for free agency, their teams are making the playoffs and they still have a good chance of improvement before the trade deadline.
Are OKC and Pels going to be sellers at the trade deadline? Let's assume that. Other team have a better combo of picks and young talent than us (f.i. Boston, LA, Philly). What do we have? A great pick (Brooklyn), a good expiring (Schump) and a decent young talent (Osman).
Kevin Love weakness are exposed, as well as TT and IT's. They are no two-way players (TT a role player), championships are won at the defensive end of the floor. KL could be an all-star but will kill both OKC and the Pels, they aren't going to need him. Three way trade? Good luck with that. IT is an expiring monodimensional player in a league stacked with great PG. TT, as said before, is not more than a second unit role player.
Let's face it. Superstars are out of reach FOREVER. Kyrie was our last chance to get them and we made a choice. I can't say that was a bad one, we got a lot, but no superstars were among them. A great all star scorer, a good 3D forward and a great pick. But no superstars. Could we turn back time, pack again the scorer, the forward and the pick and go and get a true superstar? We'll run in circle.
The best players available within our reach are those names popping up in trade rumors.
George Hill is a good name. I'd rather have Evans but they both are clear upgrade at the 2 spot. Lou Williams is not needed. I'm not sold on DJ, as I stated before, but I'm ready to chance my mind. Gasol is by far the best player, if available.
