I appreciate what you're saying and I think Howard gets too much of the blame. Whilst I have no sympathy for him as he's an arrogant bell, anyone thinking Joel will solve all our problems is being optimistic.
However no one thing will solve all our problems. All we can do is try to make individually good changes which hopefully lead to a combined, improved outcome. Joel is no worse than Howard in any way but is noticeably better in quite a few ways. There was no finer example than when he rushed out and headed the ball yesterday. The EXACT same thing happened with Howard VS Chelsea, where Jags stupidly allowed the second bounce (yes it's not just the keeper at fault), but where Howard made a complete mess of it and allowed an open net, Joel reacted smartly and cleared the danger. That is a perfect example of Joel being an improvement and a goal being saved.
It not affecting the outcome is irrelevant as it's a team game, but man for man Joel is an improvement. And I just want to see us improve.
