Either way his velocity is up to last year in his last few starts, look at his velocity chart, it fell off for a while.
It's more than good enough, the problem is his other pitches, locating the sinker and slider, slowing down the changeup.
Like most of the Phillies young pitchers, the stuff is good enough, but the command and consistency is lacking.
I don't think all can be coached up, but I suspect a number will make a big jump next year.
With young pitchers, it's often a matter of a mechanics tweak (see Nola who added 2 MPH by learning how to use his legs), or a different grip on a secondary pitch or even learning how to throw a two seamer with movement. Master a changeup, throw the slider with more spin, develop a wicked two seamer, and suddenly a marginal starter makes a big jump.
As far as the new measurement:
Andrew Perpetua of xStats.org did some testing and found the difference in fastball velocity to be about .36 mph higher league wide with the new measurement.

I'd say the consensus is about 0.5 MPH depending on the pitcher, shorter pitchers and those with less extension will get a slighly larger boost.
Just firms up 91 MPH as my cutoff for ML starters (with the preponderance of hard throwers, I'd say 93-94 for the pen except for freaks like Milner).
You can make it averaging less than 91, but you'd better have 2 plus secondary pitches to go with above average command.
Hellickson in 2016 is a good example, 91.4 (adding 0.5), but both the change and curve were plus pitches. This year the FB/sinker are down to 90.0, and the changeup and curve are less effective.
I don't think it was unreasonable to gamble on him maintaining his velocity at age 30, had he done so, the QO would have been just fine and they would have garnered a much better package.
