Speed is not the be-all-end-all of fighters.
* First of all, though, the F-22 is a USAF fighter. The F-14 was a USN fighter. Two different services, so the F-14 could not have been retired to make room for the F-22.
* The F-14's engine, the TF30, had poor reliability and was a 1960s design.
* The top speed of the F-22A is Mach 2.25; the top speed of the F-14D was Mach 2.34; a .09 Mach difference?

* The F-22 can "supercruise" at Mach 1.82, a possibility that was somewhere between a dream and a fantasy when the F-14 was designed. The F-22A also uses thrust vectoring for maneuverability, a capability the F-14 did not have.
* The radar cross section of an F-14 is somewhere between 10X-100X that of an F-22. Detecting an F-22 is difficult, and tracking by an air-air weapon near impossible.
* The Phoenix missile, amazing for its time, was designed to shoot down bombers, which aren't maneuverable. Against a maneuvering fighter it would be pretty much ineffective.
* The F-14's electrical power capability was probably pretty much max'ed out with the "D" variant, limiting avionics upgrades; the F-22 apparently still has capacity for upgrade, though building new F-22s is not likely to happen.
The F-14A was a great plane, but it was a 1960s design that did well in the 1970s and 1980s, but was showing its limitations in the 1990s and 2000s. Nostalgia doesn't win air-air fights.
