And many expect that fellow denizens of the internets would realize how simple it would be to search for such "significant" information yourself instead of charging others with doing it for you.
As such, many will likely assume that you are making a rhetorical statement by repeating such a question for hours, now, when you could have found it out quite a while ago. This accompanied by the sardonic "Ok so one" comment might help you out if you're wondering why few were willing to assist you in your tireless efforts to ostensibly support the latest addition to the Colorado Buffaloes coaching staff.
The answer to your question is that in three years Chiaverrini has four recruits to his credit. Not many, but high caliber at his position, with two essentially four-star receivers in the last two years (and two middle-ground o-linemen two years ago, showing an ability at a position of need), though this is not exhaustive by any means, as every recruit has a main recruiter, yet only about 15% of profiles will list this information. But... Tony Brown was a huge steal last year, and is probably why people are valuing his recruitment potential as highly as they are. We wanted him badly, DC pulled him away from us at the end of the recruiting cycle. The other is TJ Vasher, a four star from this class.
Both of these players are more highly rated than any WR that Walters had recruited since he arrived here. Huntley and Fields were the highest over that period of time, but they were recruited by Tumpkin and Clark, respectively. However, Walters brought in Lynott (possible that he didn't have to do much recruiting there) and Patrick Carr (we basically fell into this situation after Brown spurned Walters for TT).
Perhaps it was ultimately a "push" as their numbers are similar over the same period, but if Darrin pulls in a four star receiver for us in the next 18 months, and we have receivers not named Spruce or Fields decide to catch a ****ing pass over that period of time, I'm prepared to call it a massive, raging win.
