Top 5 HW is a stretch. I think Shogun showed a lot in that Chuck fight. He finished him, old or not, not a lot of people finish that man. I think Rashad is an elite LHW and he dominated Forrest. Forrest did ok in that match but he never had Rashad in trouble. The Rampage fight was a toss up in my mind, I think that fight showed how tough Forrest is, but he didn't show anything outstanding. I would favor Rashad, Rampage, Shogun, Lyoto, even Jardine over Forrest.
I think Forrest is a good fighter but there is no way I think he is elite ie top 5 LHW.
