I posted another part of this analysis earlier, but this is what one of the guys at Rotoviz had to say about Perriman vis a vis White: Maybe you are like many of the mainstream NFL Draft analysts who can only evaluate players by comparing them to other players. Well then, the PlayerProfiler.com Best Comparable algorithm is for you. It identifies comparable players based on Height, Weight, College Dominator Rating (share of receiving yards and touchdowns), College Yards Per Reception (YPR), Breakout Age, 40-time, Burst Score (equally weighted aggregate of vertical jump and broad jump), and Agility Score (3-cone drill plus 20-yard shuttle). Here is a breakdown of their respective prospect profiles: Breshad Perriman Height: 6-2Weight: 212College Dominator: 36.6College Yards Per Reception (YPR): 20.9Breakout Age: 20.040-time: 4.30 (accounts for +0.05 pro day 40-yard dash time adjustment)HaSS: 125.7 (99th percentile)Burst Score 121.9 (52nd percentile)Agility Score: N/AKevin White Height: 6-3Weight: 215College Dominator: 36.8College Yards Per Reception (YPR): 13.3Breakout Age: 21.240-time: 4.35HaSS: 123.4 (97th percentile)Burst Score: 123.6 (62nd percentile)Agility Score: 11.06 (61st percentile)The data indicates that Breshad Perriman’s closest comparable is Kevin White, and Kevin White’s best comparable is Breshad Perriman. Furthermore, the variance between White and Perriman is the smallest variance between two comparable WRs in the 2015 draft class. According to abilities that we can actually measure, White and Perriman are doppelgängers. Why then do 100 out of 100 NFL draft analysts rate Kevin White ahead of Breshad Perriman? Industry groupthink – why draft Teddy Bridgewater when you can have Johnny Manziel?!?! Quarterback play. Justin Holman – while Clint Trickett was a top-40 college quarterback by every measure (67.1 completion percentage, 7.8 YPA, 67.8 Total QBR), Justin Holman fell outside the top-50 in all categories, and his 56.9 percent completion percentage, in particular, made it more challenging for Breshad Perriman to impress NFL talent evaluators and sport media draft analysts.How did Holman’s struggles specifically affect Breshad Perriman’s draft stock? An ineffective UCF offense meant fewer total plays, fewer red zone opportunities, and fewer total catches, leading to fewer opportunities for highlight reel-worthy plays, forcing Perriman to do more with less (see 20.9 YPR vs. 13.3 YPR). Just one less ball thrown to a location where Perriman could go up and make a spectacular acrobatic catch is one less opportunity for a film watching aficionado to “fall in love” with Perriman’s ability to “highpoint the football” and to “look the part” of a “true game changer.” Less accurate throws not only make big plays more challenging, every inaccurate pass, that is not converted into a catch, is an opportunity for a subjective film watcher to credit Breshad Perriman with a drop. Not surprisingly, he posted a 14-percent drop rate based on Pro Football Focus’ perception of each catch’s degree of difficulty. If Breshad Perriman and Kevin White traded jerseys and quarterbacks last season, Perriman would be a top-10 lock, and Kevin White would be the “late riser.” http://rotoviz.com/2015/04/rotoviz-round-table-breshad-perriman-edition/
