Well I don't want to go over old ground but that ignores so many of his earlier achievements. Liverpool built their team around him when they were **** and did so again in 06-09 when they were pretty good.
The thing about footy is that it's widely accepted that stats are fairly meaningless for anyone except an out and out striker. This is a good thing but it does mean we get the equivalent of 55+ averaging batsmen getting dismissed as not much cop.
Gerrard's best season may well have been when he was the link-up between Alonso and Torres, then again Scholes was a better player alongside Keane, Lampard is better when Essien is there etc. Tell a player to focus on less, they will be seen to do more.
Then again, some would argue that Gerrard's best season was 03-04 where he played as a holding midfielder and single-handedly dragged an appalling Liverpool side to 4th, and into the European Cup, which they would go on to win. Of course, some would say his best year was that year they won the CL. Still, I know plenty who reckon it was the 05-06 season, or the 07-08. Oh yeah and some people who've watched his whole career reckon the Gerrard of 00-01 and 01-02 was a sight for sore eyes and that he was a big miss in the 02 World Cup.
He's been below his best this season, but he's been a fantastic individual and team player pretty much his whole career. If he didn't want to stay at Liverpool/was scared of leaving (delete as appropriate) he could have gone somewhere and won Championships but I think he's done enough to earn the respect of football fans.
