Rule: by combining, you take both original players out of their roster spots, so for instance you can’t have a Gobert/Mitchell while also having Gobert and Mitchell. I’d have to say Rubio/Korver (Rorver? Kicky?) as Ricky has the ball in his hands enough to make that more dangerous than a Favors/Korver. If I’m allotted a second one (in addition) I take Favors/Niang. Though a Jingles/Favors would be interesting because you move Crowder into the starting 5.
