Kendrick 9-9.5

Joey 8

I guess it implies pure rap skill when you say lyrically, but lyrics also implies songs/songwriting skills to me which is somewhat different to me than pure rapping.

I would consider pure rap skill to be who would spit a doper freestyle over the same beat. In pure skill I would definitely give Kendrick the 9.5 and Joey I might drop to a 7.5.
