I have to disagree with your comments regarding Delap offering nothing other than a long throw. Whilst you may have noticed that he offers little in an attacking sense (something I can't argue with) he, along with Dean Whitehead as a central midfield pairing, are vital to the way we play. Neither are particularly effective in an attacking capacity, but are two of the fittest players in the league. This showed in the first half yesterday. Your players didn't have any time on the ball. Delap and Whitehead harass the opposition with constant running and tackling. This results in us winning the ball higher up the pitch, leaving our two wingers Etherington and Pennant, and our forwards Jones and Fuller to attack. This was proving very effective in the first half yesterday, as it has done most of the season. Granted, Delap and Whitehead aren't the best players with the ball at their feet, but there aren't many in the league that are better without the ball, chasing and harrying the opposition. This enables out players who are good with the ball (Pennant, Etherington, Fuller, and Jones) to to what they do best.
They are two players that are vital to our system.
