Speed was a better player than Cahill.
Joining as a childhood blue, having won the League with Leeds only a few years prior, he was a major coup, and seemed like the ideal signing to take us to the next step.
Unfortunately, that wasn't the case. He only ended up staying for 1.5 seasons, both of them threatening relegation, and he left under the worst possible cloud after refusing to play in a game away to West Ham when he was club captain and we were struggling badly. I think we have all heard plenty of rumours why this happened, so need to go back over them, but it was a mess and nobody came out of it looking good.
He moved to Newcastle for £7m shortly after and stayed there for 6 years, ironically leaving Newcastle to join Bolton in the summer of 2004. Moyes actually tried to sign him back for Everton, but it didn't come off, and instead, we signed... Tim Cahill.
Cahill on the other hand had longevity, staying for 8 years and became a hero when we needed one. He might not have been a blue when he joined, but he was definitely one when he left. For years he was our talisman, often scoring important goals for us, including a number against the RS, and teams hated playing against him. He epitomised what Evertonians wanted and needed from a player.
In many ways, Cahill became the club legend that Speed could've been if things had turned out differently. But if we are just comparing who was the better player, and not their legacy at the club, then I would say Speed was definitely the better player. For those who remember him playing, he was fantastic. In many ways, similar to Cahill. He scored goals, was brave, and could put himself about, but he was was also technically very good.
The way he left will always leave a blemish, regardless of the facts behind the decision. His silence and ambiguity over his reasons, rather than protecting the club he loved, instead fuelled countless rumours and endless gossip, and it left a bitter taste because of how badly we needed his leadership and goals at the time. He took 100% of the blame on his shoulders and became a hate figure for many of the people left in the dark, which makes uneasy reading given the events that unfolded years later. His impact at the club was huge, but much less than it could've and should've been.
Just another "what if" Everton moment that can be added to the massive collection.
