Edgar declined rapidly? I don't think so.Thought Erick Silva would atleast be top 5 (fuck your kid jokes)
There was a big black dude from Sweden, did well in the regional scene, Papy Abedi. Did horrible in the UFC.
Thought Hector Lombard would amount to more.
Karlos Vemola had som beast like performances but was never that good.
Maiquel Falcao too.
Then we got Gray Maynard. He looked so good in the Edgar fights before he gassed. I believe Maynard is the reason Edgar declined so rapidly.
Then there's like 100 other examples. Mostly fighters who looks great in their UFC debut then falls flat.
Erick Silva for sure. He was knocking guys out, he has slick submissions, but he had bad defense, cardio.
Lombard, Brooks, Askren
Brandon Thatch
Doo Ho Choi
