I like Landry, I really do but he's not a starter in the playoffs yet.
He should play around 20 minutes as a SF imo and guard Pierce.
Allen is too slick and too clever for him, those three 3-pointers by Ray Ray hurt us big time plus on offense he's a turnover machine because of his inexperience.
SF could be ideal for him.
I'd even play Melo as SG to be honest.
