As roses is

from Lupe Fiasco – Champ Is Here (Freestyle) Lyrics on Rap Genius

This is a refrence to Andre 3000’s song “Roses” off the Outkast double album Speakerboxxx/The Love Below, where Big Boi and Andre both made two separate solo Albums, Andre’s being The Love Below. Contrary to Big Boi’s rap album, it felt like 3 Stacks went for a more R&B feel in his album. It is also the best selling Rap album album of all time, selling more than 11 Millon copies and winning Grammy’s that year.

As you can see, Lupe is stating that if you look closely at other MC’s flows, they aren’t as good as you first thought. Refrenced the "His” towards other MC’s.
