I wouldn't go that far. I think its a good gym, they have their positives and obvious down sides. For example, unless you are truely exceptional I believe some of the habits their fighters get into are likely to become an issue at the top level. For example, for Naz its fine as he's unique, but for Junior Witter and Johnny Nelson, its very unlikely they'd have faired well against the absolute best. At a lower level some of their techniques can work to their benefit on sheer awkwardness.
I liked what Brendan did regarding getting lads qualifications and teaching them to drive.... he did not just teach them boxing skills in the unique way his gym did... he gave people some life skills that they could use after boxing as well....a lot of this goes under the radar... really encouraging stuff...it gets my vote..:happy
