I love this groove. Questlove has injected this R'n'B groove with an afro-cuban feel that works perfectly on this tune. It looks a little bit awkward on paper but it plays really nice. Questlove lays down the backbeat for this groove with a cross stick/rim shot flam, getting a nice percussive sound which complements the afro-cuban influence. The accent for the flams is with the right hand which plays a rim shot close to the edge of the snare, and grace note is a cross stick with the left hand. Enjoy.
