I really like Saric for Minnesota. He would be a good upgrade for them at PF. It would be fantastic to see Minnesota move away from those two big man lineups with Towns next to Dieng or Taj Gibson. Putting Saric in there instead would help open up that offense some more. Give Towns more room to work. Keep Towns around the ball and involved in the offense more. Gives Minny another ball-handler & passer on the perimeter. A much more dynamic attack.
I am less interested in Covington. I would prefer to see Wiggins shift back to SF which is the position that I think he belongs in. So I would prefer to see Covington moved on for a true SG to play alongside Wiggins. Again, someone with more ball-handling and passing (at SG) to help open up the offense some more ... because we know Wiggins isn't giving you that.
I wouldn't be against trading Wiggins and keeping Covington instead. Just long term, I do not like the two of them together. Too limited on the wing offensively. Not enough ball-handling, passing, creative play.
