Take heart, 49ers. You’re not alone.

Plenty of other teams have repeatedly squandered high-end draft picks on unproductive wide receivers over the years.

Since 1990, the 49ers have selected 10 wide receivers in the first, second or third round. Of those 10, only three – Terrell Owens, Michael Crabtree and J.J. Stokes — have had more than 78 career receptions.

The other seven include two first rounders – A.J. Jenkins (2012) and Rashaun Woods (2004) – who combined for 17 games and seven catches with the Niners. The other five were third-round picks: Jason Hill (2007), Brandon Williams (2006), Derek Hamilton (2004), Cory Fleming (1994) and Ron Lewis (1990).

(Do you need a moment?)

The 49ers, of course, figure to try again in next week’s draft. They are expected to select a wide receiver with their first round (No. 30) or one of their two second-round picks (Nos. 56 and 61).

Sammy Watkins. Mike Evans. Odell Beckham. Brandin Cooks. Marqise Lee. Kelvin Benjamin. Davante Adams.

Recent history suggests the majority of those wideouts won’t achieve the stardom that appears quite possible before their first career snap.

Of the 183 wideouts drafted in the first or second round since 1990, 20 percent (36) have earned at least one Pro Bowl berth at their position, the lowest percentage among any offensive spot.

Granted, Pro Bowl berths are an imperfect measurement. The lack of one on a resume doesn’t necessarily mean the draft pick was a flop. For example, Joey Galloway, Amani Toomer, Johnnie Morton, Plaxico Burress and Curtis Conway each had more than 8,000 career yards, but no Pro Bowl berths.

Still, the numbers below hint at the difficulty of evaluating college wide receivers (click on links and sort by “PB”):

Percentage of Pro Bowl berths among first- or second-round picks since 1990 (Source: ProFootballReference.com):

OL

33 percent (65 of 199)

RB

32 percent (44 of 139)

Note: Glyn Milburn made his two Pro Bowls as a returner.

QB

TE

26 percent (17 of 66)

WR

20 percent (36 of 184)

Notes: Cordarrelle Patterson, Dexter McCluster, Percy Harvin and Desmond Howard made Pro Bowls as returners; Dexter Jackson is listed as a WR, but played defensive back in the NFL.
