New Wave’s Dan Manasoiu has taken a bold stance against Greg Souders, a leading advocate of the Ecological Dynamics approach in Brazilian Jiu-Jitsu (BJJ), igniting a heated debate within the community. Manasoiu, an ADCC bronze medalist and a student of the legendary John Danaher, recently responded to Souders’ public critique of Danaher’s teaching methods.

Souders, known for championing a more adaptive and naturalistic approach to BJJ training, openly criticized the foundational principles of Danaher’s traditional instructional techniques. Appearing on a podcast, Souders dismissed the idea of requiring structured knowledge to begin learning as “the craziest thing” he’d ever encountered.

Furthermore, Souders took aim at Danaher’s widely celebrated instructional DVDs, particularly his leglock series, accusing them of lacking depth. He argued that these materials repackage the same core concepts with minimal variation, sarcastically summarizing their content: “Your feet either go outside, inside, or mixed, place the leg on one side or the other, stay connected, and move your partner’s legs.” Souders even suggested that this approach could save practitioners $400, insinuating that the instructional series offers little value beyond these basic principles.

Manasoiu, however, refused to let these comments go unchallenged. In a fiery social media post, he accused Souders of spreading “misinformation” and “diluting the essence of the sport” with his “flawed concept” of the Ecological Approach. Manasoiu’s defense of Danaher’s methods was both passionate and unyielding, pointing out that Souders lacks significant competitive accomplishments to back up his critiques.

Manasoiu’s post also called for clarity within the Jiu-Jitsu community, stating it was time to “separate fact from fiction and put this discussion to rest.” He proposed a live-streamed debate, inviting Souders to defend his claims before the broader Jiu-Jitsu audience. “The Jiu-Jitsu community as a whole will thank [him] for finally addressing this and setting the record straight,” Manasoiu declared, emphasizing the importance of addressing what he sees as misleading rhetoric.

In one particularly poignant section of his post, Manasoiu wrote:

“For thousands of years, all of human progress across every culture and discipline has been built on the foundation of passing knowledge down through generations, refining and improving it over time. This approach completely undermines that tradition, discarding hard-earned wisdom in favor of empty rhetoric that does nothing but confuse and mislead serious practitioners.”

Tom Deblass also commented about Souders:

“He has an arrogance about him that is very irritating. Im all about positional training with specific goals in mind. Fight from half guard both people looking for underhooks. Start in the triangle position and look to hold without allowing your opponent to escape while your opponent tries to escape. I simply don’t like the arrogance. I met him in person once or twice and he’s always been kind. However he talks shit online and i don’t get it. People are entitled to their different approaches, but don’t sh*t on people who have proven themselves for decades.”

The feud between advocates of traditional teaching techniques and the Ecological Dynamics approach isn’t new, but this exchange has undoubtedly intensified the ongoing debate. Souders’ criticisms challenge the established norms of BJJ instruction, while Manasoiu’s response highlights the value of structured, knowledge-based teaching that has been integral to Danaher’s success as a coach.

As the Jiu-Jitsu community watches closely, the prospect of a live debate between Souders and figures from the traditional camp could bring much-needed clarity to this polarizing discussion. Whether such an event materializes or not, the tensions between these two philosophies continue to fuel important conversations about the future of BJJ education.
