Right, I've only just seen this thread so now for my tuppence-worth!
We got stitched up royally by Rennie on Saturday. Much as has been pointed out above, Carroll saw the shot take place, but by stepping over the ball Parker IS interfering with play - the lino got it right BUT (and this is the big issue with Rennie) the ref took centre stage by overruling him.
A good referee is one that you don't notice, you can't say that about Rennie and you can't say that about Graham Poll (we've had both in the last two games, both to our detriment). Ultimately it completely changed the face of the game, and from cruising at 2-0 we were ultimately left hanging on for a point.
Saying that, Davenport's "goal" that was chalked off.... what was the difference between that and Peter Crouch's against Trinidad & Tobago in the World Cup?
He did however get the penalty decision spot on - but that wasn't exactly the toughest decision of the afternoon!
As for the offside rule as a whole, I know a lot of rules have been changed to try and make the game more entertaining, and more attacking, but there is such a grey area with offside now that I for one would like it to go back to what it was - if you're in an offside position, no matter where you are on the field of play, then you are offside, interfering or not.
Not exactly rocket-science now is it?!
