Pitching velocity

You do whatever works for you. There are a few pitchers who have dropped their 2 seamer and gone back to throwing hard with great success. I believe Greinke and Verlander.

These things often run in cycles...

...Small slice that I see...but am seeing slightly more consideration given to "pitchers" this year in the recruting process than in the past.

In MLB, the passing of the steroid era is having an impact on the high 90's phenomenon. We're back to where that's truly exceptional instead of having one or more guys per team throwing that hard. Since the primary advantage of speed is to be faster than what the batter is used to, if the average fastball drops to 88-89, then you can have guys blowing it by you at 92-93, whereas if average is 91-92 you need to throw 95+ to really whiff a guy. And yes, I'm seeing that lower range in effect with the exception of the rare birds like Verlander.

In college, you may just now be noticing that speeds topping out in the 88-90 range are common, and it's not unusual to see fastballs in the 85-88 range even in the CWS. I even saw So. Miss put in a RHP with no real breaking pitch and a fastball in the low 80's, which made me wonder how they ever got this far. But generally, I haven't seen any big change in the college situation; it's pretty much been this way for as long as I've paid attention to it, which admittedly is only about the last 5 years.

If all college pitchers could throw 92+ and all college hitters could hit that, then they'd all make it to MLB. But they don't, do they? You have to expect them to be at a lower speed than their MLB counterparts, though there are exceptions who continue to be the top prospects.
