Maybe.
When you are a fat f*** like I have been at times, you can lose 10 - 20 lbs and not look any different. In fact, the only way I knew that I was losing was by my belt.
A guy like Pablo needs to lose about 40 lbs before he will look noticeably thinner. I know from experience. And so do some of the other men on this board.
To me, he looks to be at or around his 2015 spring training weight.
Can he still be an effective player? I would hope so. However it should go without saying that the chances of seeing great play from him would be much better if he lopped off a s*** load of weight.
Anyone who says otherwise has not been fat or obese. As a pedestrian I can tell you that being that fat effects every aspect of your life. Like putting on clothes and shoes, getting into and out of a car, going up and down stairs.
It would seem logical, therefore, to assume that an athlete who is required to do so many strenuous activities would see some decline in ability.
That's just the way that it works.
Hopefully he won't suck as badly as in 2015.
