As they say about any evaluation system, its only as accurate as the information that gets put into it - which in this case is a matter of opinion.
JPA may not be fast, but he is certainly one of the best leapers in the Prem, and was considered by many as one of the overall the best in the air last season.
His control is well regarded (ask John Terry and William Gallas or the Pompey defenders he skipped around), but this year he has consistently been double teamed by centrebacks, and its hard for any striker to control in those situations.
You don't consider his passing at all, or his build up play and awareness, which are very relevant elements to a complete striker's game. All spaces in which he excels. Note that in yesterday's game, in which we were awful, and he has been singled out for poor play - we had two scoring opportunities (a penalty and another that should have been called), both were created by the guy with the 9 on his back.
He scored several crackers from distance last season, that I think speak to his ability to score from distance as well.
With regard to killer instinct, I think you're dead wrong. He finds ways to score sometimes that people never expect (like a backheel against Argentina when being double marked by Samuel and Ayala).
He's had a poor season, and his form is off, but that doesn't discount the quality he's shown in the past at Villa, for his country, and for River Plate. The guy is a class professional, and exceptional football player.
These are differences of opinion, and your welcome to yours. I appreciate your putting together a framework to present your view, but I (and I suspect others here) utilize the same framework and reach a different conclusion.
top post....
but then to add to that, theres also his mental qualities...
his mental strength, which was highlighted after he came to us and stuck by us through arguably the toughest period in his career apart from this season, but again highlighted this season with wanting to take the second penalty against fulham... may players would have hid and not have the bottle to take that....
loyalty.. had the opportunities to move and he didnt...
again, i reiterate, he has been poor this season, but without a decent preseason and playing most of the season without full fitness and sharpness, it isnt his fault when the squad situation is the reason hes playing in the first place....
and again, he isnt the only one to be suffering for the very same reason....
