Its funny how year after year, the same old teams wind up shooting themselves in the foot and snatching defeat from the jaws of victory. Talent ? yes...Everton has talent. But talent only gets you so far. Potential ? Yes, Everton has potential. Potential only gets you so far. Every year at the Kentucky Derby you see 19 talented colts with potential puke all over themselves as they try to conquer one extra furlong.
To win titles, you need a coach who will never be satisfied with less than a players' best, make wise and different personnel decisions, yet doesn't go so over the top as to lose his team (e.g. Mourinho). And all of this despite their own personal shortcomings. cf Lombardi, Wooden, Belichick.
Funny how the same NFL teams such as the Rams, Browns, Raiders, Jets, Bills, Texans, Jaguars, Dolphins, Giants, Colts and Chargers struggle year after year despite their TV money. The upshot is that he's just another manager and he'll provide thrills, but until he wants to go out on a plank (personally and professionally) to become great and make those around him great, he'll never see titles with Everton.
