Box of worms opened there. While I don't agree fully with what you've wrote you must some pertinent points like.
There would be a natural bounce of optimism for the club on winning the FA Cup but ultimately it's not going to give us the money we need to sign the couple of players we need to make a sustainable different.
There's no club in the land than can look down their nose at an FA Cup win though, a wonderful trophy.
For the sake of nostalgia it's a great trophy due to history attached to it. But until it has a Champions League spot for winning it, the FA Cup will continue to be very much secondary for any serious club around the top eight of English football.
If we won it this year, it'd be very, very surprised if the fixture congestion (with replays and all, you're looking at between eight to ten games potentially) didn't eliminate us from a serious chance of finishing 4th.
Look at Liverpool now. The sole reason why I'm 99% certain we'll finish comfortably above them is because the beauts still have the Europa League to contend with. They've played ten more competitive games than us already this season thanks to that crap competition that if you won only generates as much income as simply qualifying for the Champions League does.
I want Liverpool to progress as far as humanly possible in the FA and Europa League, because every game they play is like a shot in the heart of any chance of finishing 4th. Same with Tottenham, Arsenal, Chelsea... the lot of them. If Everton played
40 games flat (1 FA Cup 3rd Round defeat and 1 League Cup 2nd Round defeat) a season, and Liverpool/Spurs/Chelsea/Arsenal played close to or at the theoretical maximum of
81 games a season, I'd be over the moon.
Why put yourself in a sub-standard competition with depleting prestige and minimal prize money just to dent your chances of actually qualifying for the big time.
The FA Cup, League Cup and even the Europa League are the preserve of the Newcastles of this world. The smart club would jump out of the domestic cups at the first opportunity and, at best, compete in the Europa League ONLY if you were unfortunate enough to qualify for it.
Money talks in modern football - that's the be all, end all of the matter. I hate modern football, I wish we could go back to the romanticism of a "good old cup run" like in 1995, but those days are dead.
