I think it strange that people can be down on Edwards or Langford in any way. Remember, both are now Celtics because Danny fleeced the Sixers into giving up extra assets just to assure they got the players they wanted. The Sixers desperately wanted Markelle Fultz in 2017 and Matisse Thybulle this year and Boston was in front of them in both drafts. So, Danny ended up trading down in both drafts with Philly and ended up with trades that ended up being:
Jayson Tatum and Romeo Langford for Markelle Fultz.
Grant Williams and Carsen Edwards for Matisse Thybulle
Now, Ainge most likely would have taken both Tatum and Williams in the draft positions they traded out of, but Philly thought their guys would be taken, so they gave up extra assets just to get their guys.
Their guys ended up being Markelle Fultz, a complete bust of a #1 pick, and Matisse Thybulle, who, it can be argued, showed less in Summer League than either of the two guys the Celtics took.
The Celtics got their guys, Tatum and Williams, but parlayed Philly's impatience and uncertainty of getting their guys, into Romeo Langford and Carsen Edwards. Now, Langford, we have not seen because of hand surgery but he was a top 5 high school recruit and, along with Edwards, probably the two best guards in the Big Ten this year. Edwards had a stellar Summer League and earned himself a nice 4 year deal as a 2nd rounder. Both have high ceilings and could be real steals for where they were taken in a bad draft.
Regardless, they are bonuses gotten because Danny convinced the Sixers they should give up other assets to get their guys. If both player's become rotational players or better(all the way up to stars) then Danny just completed two heists upon their old rivals.
So let's all cheer for and hope that Romeo and Carsen become great players and long term Celtics. That way Philly can see the great players they gave up, to get, hopefully, two complete busts.
Maybe this makes everyone feel better about Sixers stealing Horford.
