On the surface Thielen built on his 2017 breakout last year, cementing himself as one of the league's top receivers with a 153-113-1,373-9 line and 9.0 YPT (10th). But the shape of Thielen's efficiency and overall production changed under quarterback Kirk Cousins. Instead of making big plays, he simply caught a higher percentage of the passes thrown his way. Despite 11 extra targets, Thielen had two fewer catches of 40-plus yards and three fewer of 20-plus. And even though Thielen maintained his solid per-target efficiency, his YPC dropped from 14.0 in 2016-17 to 12.2 last year. In full PPR, perhaps this is for the best. Thielen's average depth of target was a modest 9.2 yards, helping him to a whopping 73.9 percent catch rate, the 17th-best mark of all time among 100-target wideouts. But the Vikings offense took a step back in 2018, and offensive coordinator John DeFilippo was replaced by Kevin Stefanski. While it's unclear how Stefanski might change the scheme - he's only 37 and previously the quarterbacks coach - the Vikings' dink-and-dunk style might have been dictated as much by a shaky offensive line as it was by coaching philosophy, i.e., we could see more big plays from Thielen if it holds up better in 2019. (To that end, the Vikings used their first draft pick on a center, their second on a tight end and their fourth on a guard. They also signed guard Josh Kline and get center/guard Pat Elflein back from injury.) At 6-2, 200, with 4.45 speed, Thielen is a good athlete who has excellent hands (only two drops all year) and strong route-running skills. He was also used a good deal in the red zone (21 targets, 6th), and inside the 10 (nine targets, T-8th), meaning his spike in TDs was no fluke. Stefon Diggs is once again Thielen's only major competition for targets, but tight end Kyle Rudolph does siphon away some red-zone looks.
