In the 2014 draft we used our first-round pick (a primo pick at #7) on a RHP whose FB sat 91-94. Nola was our best draft pick over at least the past 15 years, giving the Phillies 35 rWAR and quickly arriving at the major league level. FB velocity is an important weapon, but so is exceptional command and off-speed pitches. I count Nola in most of his years as an ace, in part because what his number of IP contributes to team success.
But, once again, everyone is dug into absolutist positions and quoting facts like how many of the top 10 SPs in baseball have a FB sitting at 95 and plus, when the discussion began about ranking qualities of far, far lesser pitchers like Lazar. Truth is, not many SPs sit above 95 with their FB and baseball needs about 200 SP in the majors every year. There is room for the guys with control and plus off-speed pitches as 3-4-5 guys in the rotations of even good teams. I'd love to have a SP on the Phillies with a plus knuckleball, even if his FB can't through the 90 mph barrier. Superior spin rate can also make a 92 FB superior to a 95 FB. So can exceptional deception and/or extension.
It's easy to select young prospects based upon velocity, but that misses a lot. It;s become a stereotype, like pitcher height used to be. If you're going to select prospects for signing or further development primarily based upon velocity, then you don't even need scouts -- just give a velocity meter to a fan.
