The Los Angeles Lakers are not interested in Gordon Hayward if they were to trade Russell Westbrook to Charlotte Hornets.
They are more interested in Terry Rozier as the main piece in a trade, per Marc Stein.
"The Lakers are unlikely to consent to a Charlotte trade headlined by Gordon Hayward — not after Hayward's first two seasons in Charlotte have likewise been injury-filled. The Lakers surely understand that they need to factor in durability if they are taking on long-term money, which suggests that Terry Rozier would have to be the Southern California-bound headliner if the Hornets and Lakers eventually progress to serious trade talks." - Marc Stein of Substack.
Hayward has two years left on his deal and is owed upwards of $61M.
