Read Robbie Fowler's book and your question will be answered. He would never play for Everton and both Fowler and his Dad were Evertonians once. Now they both cannot stand the club because of the amount of abuse their so called fans have given him in the past. All the rumours about drugs etc.... the smackhead taunts, all a myth perpetuated by Everton fans. Fowler has also took a couple of smacks off lads while out in Town drinking, one in the Wonder Bar and another in that hotel on Paradise Street which has been knocked down. I can't say whether or not they were opposition fans or not but I will try and clarify that later on.
But Everton rejecting Fowler? Don't make me laugh, he wouldn't have given them the time of day in the first place. Did you see Anelka's reaction last week when he was being linked with them? Imagine that, multiply it by a factor of one thousand and then you would get Robbie's reaction on being linked to Everton.
It's all in the book. A very detailed chapter all about the drug rumours and his feelings on Everton. I'll have a quick read of it later and summarise it if I get the chance.
