He is a good bodybuilder, nobody's refuting that. Mostly because he can come in at his best.
Phil's back double bi is very good and here the width and proportions looks good even to me.
But anyone can have one good pose, that is not bodybuilding. Almost every other shot (fdb, all lat spreads, ab shots, relaxed shots etc) is not so impressive. And I'm not even talking about comparisons, but rather when he is standing alone you see the weaknesses.
With his arms you'd think he should be able to pull an awesome front double bi like Arnold or Yates. But no, his chest and overall width just makes this pose a bad one for him. There is no hiding in front double bi as we know.
The back double bi - not to take anything away from it - is better because his chest is thankfully hidden. He does have a real developed back that is impressive detail-wise, and that draws attention from the width.
And the fact that he can lean 45 degrees back in this pose compared to the fdb makes his v-shape much better.
I don't think he will get his due in the future. I think a better Mr O will come along and the opposite will happen. The hype will be gone and the new generation will not understand how Phil was so popular in the 2010's.
