The contest was between Jay and Phil, and they both had very different types of physiques, each with their own flaws. Jay was the defending champ and wasn't off enough for Phil to knock him down. Nor did Phil outmuscle Jay. Also, Jay improved from Fri - Sat, while Phil went the other way, although not by that much.
Dex has been sharper and fuller, and is not really complete. He has poor calves and looked smaller than he's ever been, which is what cost him 3rd place over Branch, who had too much muscle and conditioning.
No way did Dex deserve the title this year, sorry mes.
