Danny would really need to have his eye on somebody if he did this and I think we have enough picks to maneuver around, but your point still makes sense.
Olynyk is due to get paid next season. Now, he could have a year like this one where he showed to be a decent rotational player with some ill-timed health issues, or he could step in for the departed Sullinger, play a larger role, and remain injury free, and be set to make a lot of money next year (when the cap is even higher!). I would just hate to be the team that paid Olynyk $15M+/yr.
