As much as I liked Forrest, he was never a great fighter in terms of ability. He had tons of heart and will, but he wasn't fast, strong, powerful, or technical.
He was good at a lot of things, just not great at anything in particular. He did have good leg kicks when he used them.
He benefitted as much as anyone from a weird time at light heavy.
His marquee wins are over Shogun, a questionable decision over Rampage (I think I had it for Forrest when I watched it, but can't really remember), and the TUF finale.
His bad losses which are sprinkled throughout his career in the UFC are KO losses to Silva, Rua, Evans, and Jardine.
The man was a fan favorite, just not elite.
Gane's resume is much more impressive with notable wins over Rozenstruik, Volkov, Lewis (KO), and Tai (KO).
Only loss was a Decision to Francis.
I like Forrest, but most people knew that he was being set up as a lamb for slaughter by fighting Silvia.
His striking was miles behind Silvia and he was slower than just about anyone Silvia had fought and he didn't really have KO power.
