The Oklahoma City Thunder has asked the Miami Heat for multiple young, valuable assets in trade conversations involving their franchise point guard Russell Westbrook, but the Heat have refused, according to Barry Jackson of The Miami Herald.

Among the pieces, OKC has asked the Heat to include rookie guard Tyler Herro in the proposed trade, but the Heat has been very reluctant to do so, after the Kentucky product has impressed widely around the Las Vegas Summer League.

Herro recently signed with the Heat on Wednesday and he cannot be included in any trade for 30 days, but that isn’t viewed as an impediment to get that deal done.

The Thunder have reportedly asked the Heat to include two among Herro, center Bam Adebayo and forward Justise Winslow, whom the Heat used as a point guard for part of last season. The Heat also refused to include Adebayo in any deals, whom Erik Spoelstra ranked among the best centers in the league in the final months of the 2018-19 campaign.

Miami is hoping to add Westbrook, but the Thunder’s specific demands have caused talks to stall as of Wednesday.

So far it has been a hard no for Herro and Adebayo, but the Heat could be open to dealing Justise Winslow, who they’ve viewed as a core piece for the team. Yet Miami added Jimmy Butler in a multi-team sign-and-trade with the Philadelphia 76ers, who gives them that certain two-way dynamic at the small forward spot.

The Heat are one of the very few teams that can acquire Westbrook at the moment, and it looks like the urgency for a rebuild and change of scenery could force both of these teams to re-engage talks in the near future.
