It's not about him being fine with it. It the same thing with Hood. Why spend that money on a 6th man when you can put it in your starting lineup? Having Fournier on the books might interfere with being able to extend Rubio or sign some other UFA in 2019.If he is locked into his contract he may be fine coming off the bench or at least warm to the idea. I think a rotation of Rubio, DM, Evan, Ingles, Royce is diverse and has some interchangeableness (not a word). If Exum is healthy we have a lot of options 1-3... with Royce playing small ball 4 sometimes.
If the cost is AB and a second I'd do it... I doubt they would take it unless they think Evan helps them win too much this year.
