Sure, you can miss with any pick if you suck at drafting or just get unlucky with injuries.
But Cooper Kupp might be the best WR in football and he was round 3.
Scary Terry R3.

It's pretty easy to hit on a talented WR in round 3. A lot of positions are far harder to find NFL caliber guys outside round 1 or 2.
Dallas should probably look to draft a round 3-4 WR every year.
Especially if they are going to keep stockpiling picks to maximize cap dollars.
Tyreke Hill just got paid QB money as a former 5th round WR.
Again, it's not that easy. It's a 50 percent hit rate. That means half the picks fail. Sure, it's easy to point out the good ones ... the reasons you keep taking receivers in the third round. But thinking I can just get one and it'll work out just doesn't fit the evidence. You can say if you can't find a good one, you just suck at drafting, but that isn't true. Both good and bad drafting teams miss.
Let's just take a 10-year period (2010-2020) since it's harder to judge receivers who've been in the league only a year.
2010 (4 hits, 4 misses)
Damian Williams (Tennessee) miss; 107 catches, 1,327 yards for career
Brandon LaFell (Carolina) marginal hit; never had a 1,000-yard season, but came close
Emmanuel Sanders (Pittsburgh) hit; three 1,000-yard seasons
Jordan Shipley (Green Bay) miss, had 79 receptions for 858 yards in his career
Eric Decker (Denver) hit; had three 1,000-yard seasons
Andre Roberts (Arizona) hit; maybe not a success as a receiver, but an All-Pro as a returner
Armanti Edwards (Carolina) absolute miss 40 rec. 281 yards for career
Taylor Price (New England) absolute miss 5 rec., 80 yards for career
2011 (0 hits, 4 misses)
Austin Pettis (St. Louis) miss; 107 rec., 1,034 yards for career
Leonard Hankerson (Washington) miss; 107 rec. 1,048 yards for career
Vincent Brown (San Diego) miss, 133 receptions, 941 yards for career
Jerrel Jernigan (NY Giants) miss; 39 rec., 492 yards for career
2012 (2 hits, 2 misses)
DeVier Posey (Houston) miss; 22 catches, 272 yards for career
T.J. Graham (Buffalo) miss; 61 rec., 794 yards for career
Mohamed Sanu (Cincinnati) marginal hit; no season with more than 67 catches, 838 yards
T.Y. Hilton (Indianapolis) big hit; five 1,000-yard seasons
2013 (3 hits, 2 misses)
Terrance Williams (Dallas) marginal hit; no season with more than 53 rec., 840 yards
Keenan Allen (San Diego) big hit; five 1,000-yard seasons
Marquise Goodwin (Buffalo) marginal hit; no season with more than 56 rec., 962 yards
Markus Wheaton (Pittsburgh) miss; 110 rec., 1,559 yards for career
Stedman Bailey (St. Louis) major miss; 59 catches, 843 yards for career
2014 (2 hits, 2 misses)
Josh Huff (Philadelphia) big miss; 51 rec., 523 yards for career
Donte Moncrief (Indianapolis) marginal hit; bests 69 rec., 668 yards
John Brown (Arizona) hit, two 1,000-yard seasons
Dri Archer (Pittsburgh) absolute miss; not sure why he's listed as a receiver, so I'm not going to count him in the total; had 7 rec., 40 yards in career
I'm going to quit there because I'm putting a lot of work in for something you will probably either ignore or dismiss. The numbers (11 hits, 14 misses) say there's even less of a chance of hitting on a receiver in the third round than what I've said, and the chances of hitting on a star receiver are very low. Out of 25 players, only 5 had/have had 1,000-yard seasons in their career.
The odds are actually against Tolbert succeeding, but we've had pretty good luck with third-round receivers at least being decent contributors. I'm just saying that I don't know if we should absolutely count on that continuing. I'm keeping my fingers crossed.
