The pace probably would have defeated Scholes but I think that you are under estimating what a player of that ilk brings to the team by making themselves available for passes at all times. Carrick would have been better than Parker for example because we simply needed someone in those areas to hold on to the ball.
Having a playmaker in there wasn't going to make the players around him move any more to receive it. Hodgson's team is static because this is how he sets them out. Rigid chains in both attack and defence. Players don't have much license to leave their zones which is why they aren't showing much for the ball.
It would have made a difference to have someone more comfortable spreading out play over 20-25 yards, but the whole 'holding on to the ball' thing I think wouldn't have made much difference. The major reason for the inability to retain the ball was that it wasn't a priority.
I still feel that Gerrard's style become redundant when you make that step up in class and face a team that can starve you of possession.
I don't think it becomes redundant, but it does necessitate having a distributor in there alongside him.
Would you not say that Benetiz got the best out of Gerrard by playing Alonso and Mascherano behind to cover up for the gaps that his style brings?
Not really. First of all, I think it's completely misleading to suggest that a player behind the main striker 'leaves gaps'. And although Gerrard/Alonso as a pairing might not be all too re-assuring defensively against the top teams it was more than adequate for 80% of the teams we'd face in the prem. If Carrick and Giggs/Scholes can dominate the league without defensive worries, Gerrard and Alonso aren't a concern in that regard.
It's not coincidence that Rafa started every season bar his last with the premise that Gerrard was supposed to play central midfield and he was only moved elsewhere to plug the obvious gaps that would show elsewhere in the squad (and Alonso/Masch/Hamann/ meant that gap didn't exist in central midfield).
It got the best out of the team but this was as much a case of us being able to field our best players as it is 'gerrard's best position'. In 2006, his best position was on the right, because it meant not having to play fecking Sissoko on the right. In 2009, it was behind the striker because it meant we could field both Mascherano and Alonso in midfield and we had no one as good up front (Keane was just rubbish).
I think in either case, if we had had a player of similar high quality in the position Gerrard moved into as we did in the position he vacated, we would have been better off with Gerrard in midfield for most games. Too often we simply didn't have enough quality players going forwards to break teams down.
And contrary to popular perception, Gerrard actually played as many games in central midfield in 2006 as he did on the right and scored more goals and had more assists from that position. And some of his better performances these past two seasons have been ones where he has had to play a disciplined game against top opposition in central midfield (including against your lot), though that perhaps is more suggestive of the fact that his matchwinning performances have become rarer (not in the least due to injuries).
I think his best position is behind the striker, because it leaves you with less of a jigsaw to get right in midfield. Alonso/Gerrard lacked defensive strength against the best teams, Gerrard/Mascherano needed a playmaker (this combo never really worked). And by now, his mentality has been coached into that role as well. But he has had many great games in central midfield, same as he has from the right.
As far as I am concerned, it really is more a case of 'how can we field our best players' and the fact that Gerrard is so versatile he can step into any of those three positions than it is a case of 'where is Gerrard weakest'. For Liverpool these days, I'd prefer him on the right of midfield (assuming Kenny's 4-4-2-ish formation) for the same reason.
