BEST FIRST-ROUND DRAFT PICK: DT Joe Greene. Before Terry Bradshaw, Franco Harris, Lynn Swann, Troy Polamalu, Ben Roethlisberger, there was Joe Greene.

BEST SECOND-ROUND DRAFT PICK: LBs Jack Ham and Jack Lambert. Taken three years apart — Ham in 1971, Lambert in 1974 in a draft class that eventually produced four Hall of Famers, not including undrafted rookie Donnie Shell, who will head to the Hall this fall.

BEST LATE-ROUND DRAFT PICK: WR Antonio Brown. There was a time, believe it or not, when Brown wasn’t an all-world talent with a penchant for self-destruction, but a sixth-round pick hoping to carve a niche in the NFL.

WORST FIRST-ROUND DRAFT PICK: LB Huey Richardson. The list of decorated Steelers linebackers is long. Richardson is not on it. Taken 15th overall in 1991, the team hoped Richardson could pair with Greg Lloyd for a top pass-rush tandem. It never happened. .

WORST SECOND-ROUND DRAFT PICK: DE Willie Fry. There have been higher-profile busts (WR Limas Sweed in 2009 anybody?) but Fry’s failure to gain traction remains a mystery.

BEST DRAFT TRADE: The Steelers have typically played it safe with their first-round picks, content to settle into their allotted spot and let the scouts do the work. Then again, there was nothing typical about Polamalu. Pittsburgh’s front office was convinced the instinctive and well-coiffed Southern California safety was the missing link on a defense frequently good but not quite great.

WORST DRAFT TRADE: How about weirdest? The Steelers sent two picks to Green Bay in 2007 to take Daniel Sepulveda — a punter — in the fourth round. While Sepulveda was serviceable when healthy (rarely a given), trading an extra pick for a position that’s among the most replaceable in the game is odd.

DID YOU KNOW THEY ONCE DRAFTED?: Byron “Whizzer” White played just one season for the Steelers, though the first-round pick in 1938 was hardly a bust. He led the NFL in rushing as a tailback, then left to attend Oxford University on a Rhodes Scholarship. It was a sign of where White’s true talents lie. White went into law and served 31 years on the U.S. Supreme Court.

LAST YEAR’S PICKS: (Round, Name, Position, School): 1st, Devin Bush, LB, Michigan; 3rd, Diontae Johnson, WR, Toledo; 3rd, Justin Layne, DB, Michigan State; 4th, Benny Snell, RB, Kentucky; 5th, Zach Gentry, TE, Michigan; 6th, Sutton Smith, LB, Northern Illinois; 6th: Isaiah Buggs, DT, Alabama; 6th, Ulysses Gilbert, LB, Akron; 7th, Derwin Gray, OT, Maryland.
