Houston would want something like Siakem + multiple 1st rounders or pick swaps or whatever. I wouldn't touch that at all. Harden is 31, and isn't really a team player, vs Siakem who is 26 years old, and does play a well balanced game.
I don't see it making us a legit top contender right now, and it's definitely worse for us longterm.
1. Yes he absolutely is, he was part of a big 3 that made the Finals when he was only 22 years old and was on that stacked 2012 Olympic team. On a team with KD and Westbrook he was the primary ball-handler in case you want any indication as to the level he is on offensively. Swapping Siakam for Harden alone would make the Raps a top 5 offence.
2. Harden is 31 and the Raps would have him for 2 MVP caliber seasons.
Siakam would give the Raps what? Can he shoot well as a 1st option? Can he pass well as a 1st option? Can he dribble well? Does he have any move other than spinning? And oh btw that's the guy who's your highest paid player of the future.
You're saying you'd rather have 5 seasons of a 26 year old 2C over 2 seasons of a 31 year old top 5 C. This isn't hockey where depth wins in the playoffs...it's star power. It's like Lebron and the Cavs taught some of you nothing.
Staying with Siakam caps the Raptors ceiling. Harden gives them a puncher's chance at the finals at least. The Raptors lost game 7 against the Celtics in the last minute and Siakam played like trash all series. You're replacing that dude with a one-man army on offence and a very good defender in the post despite his reputation.
Siakam's "well balanced" game? LOL he was the 2nd or 3rd option on a team that won the chip. You could argue Lowry played a more important role or even FVV once it was the ECF. You seriously think Harden can't do what Siakam did as a 2nd option in his sleep?
In 2018 Harden + Paul took the Warriors to 7 games in the WCF, those same Warriors swept Lebron in the finals, who happened to sweep the Raptors that ECSF.
Why do you think the Pacers took the Raptors to game 7 a couple seasons ago in the 1st round? Despite the Raptors depth PG13 was by far the best player on the court. The Nets series at the beginning of the Lowry era? Same thing (Joe Johnson, D-Will, KG and Pierce >> DD and Lowry). Wall and Beal lead the Wizards sweep over the Raps because at his absolute best DD just isn't on the level of the Wall, Beal or Lowry.
