This is a great interview with Marcelo from 2011.
This is a full 25 minutes of Marcelo opening up about his training from when he was a teenager up to the present (2011). He talks about which he thinks is better drilling or rolling, how his game has evolved over the years and what he believes is required to excel at Jiu Jitsu.
This video has kind of been under the radar, maybe because it’s not edited as cool as some others but there is a lot of great stuff in here. Check it out below.
