John Hendricks career spiral index:
1) left his entire Team (team Takedown) over money dispute
2) lost head coach and mentor Marc Laimon in the fallout
3) has been his own coach for the last three years
4) got increasingly out of control eating in-between fights
5) waded into his mid-30's (read: you get old fast in MMA)
There really isn't anything that points clearly to Johny being on PEDS and if you know the above it doesn't seem odd how things have gone for him.
When he fought Wonderboy he showed up lean and ripped, clearly muscled. He was running his own camp however and had no game plan and winged it to horrific results. This is USADA Hendricks weighing for fight night 82 against Thompson. Do not tell me he looks like he's lost muscle mass.
I feel pretty confident if we rolled out Martin Kampmann and Jon Fitch he could still knock those guys out.
As it turns out, Wonderboy is a much better fighter than they were.
