I think the problem of many is believeing he was over rated in the first place. He wasn't Messi, Zidane or any other speedy, technique drenched midfielder. However he was the best in the world at being able to put a pinpoint cross in without the need to get that yard of space.
He would put crosses in when no other player in the world would have got it past the defender and if that means only 5 pinpoint crosses a game that is not to be sniffed at. Indeed if you have Sheringham, Shearer or the like on the end of them you will score 3+ from those 5. If it's Andy Cole (my namesake) then you'll still get 1 from the 5.
I see teams as a machine and in a machine some of the seemingly unimportant parts do the most effective job.
We must not confuse what we think of the 'Beckham roadshow' with the reality which was what he did on the pitch. The off field stuff was nonsensical. the onfield stuff, the reality was that he was the number one right winger in the world for a long time without ever being pacey, without ever being able to beat a player. Didn't matter because he didn't need to beat them because of that special gift.
On the caps thing I agree. I don't think if we are just saying that caps = ability then no he isn't the best ever outfield player however that is all dependent on choices. Beckham got most of the caps deservedly through talent. The others he got because every time the manager (McLaren/Capello) tried to replace him the replacements were not as good and also without him doing that workarate in the midfield showed that he had been covering for all the others in the midfield for years.
Bentley wasn't good enough. Lennon was great speed wise but then couldn't cross (see comment above), Walcott apart from 1 game was similar to Lennon. So Beckham ended up getting those sub caps as a backup. Makes sense when you are blooding youngsters that weren't doing the job to have him there just n case. I would suggest he should probs have been playing from the start in those sub games because he was still more effective than the replacements starting ahead of him. They should have been coming on as subs.
So if caps = was he the best ever outfield player? No he wasn't the best ever however caps is not about that, caps depends on the alternatives of which there were none and even now aren't overly abundant.
However I am open minded enough to know that each person sees things a little differently (not as far as post on page 3 which belies belief) and freely admit that I am not a fan of Lampard. Scores a lot yes but I think he is vastly overrated, and his bombing forward all the time means others have to do a huge amount of work in the space he vacates as well as shooting on site rather than making additional goals.
Have been overjoyed to see Barry (who I've always rated) and Parker mean he is now sub only for England.
