Offensive rebounding is "blue collar" basketball at its best.
Collecting your own team's missed shots happens because of a lot of hustle and wrestle and work.
If we were talking the NBA, we would be mentioning players like Anderson Varejao and Joakim Noah.
More than just coincidentally being in the right place at the right time, most players who collect a lot of offensive boards do so with playing hard and playing smart.
They watch from where shots are being taken, anticipate the angles and bust their tail to get to the spot where the ball is most likely to come off if missed.
Here is a quick look at college basketball's Top Ten offensive rebounders for the 2012-13 season.
James Padgett may not be a big-time player yet, but he is headed in the right direction.
Padgett went from being a sparingly used bench player to a regular minutes guy for Mark Turgeon and the Terrapins.
The 6'8" forward from Brooklyn pulled down 107 offensive rebounds as a junior, which accounted for more than half of his overall rebounds (5.8 RPG).
If the ball goes up, you better put a body on Pierce Hornung because he is going after it.
Hornung's game may never be described as "pretty", but he is all about determination and having a non-stop motor.
The 6'5" rising senior forward led the Mountain West last year in steals and was the conference's No. 3 rebounder behind UNM's Drew Gordon (No. 6 in the nation) and UNLV's Mike Moser (No. 10 nationally). Not bad company, right?
The fact that Hornung pulled down 3.6 offensive rebounds per game for the Rams is a testament to his hard work and focused effort.
Augustine Rubit may be an undersized PF (6'6"), but that doesn't stop him from banging on both ends of the court.
Because of his effort on the offensive glass, the rising junior was the Sun Belt's leading rebounder (9.2 RPG) and No. 2 scorer (15.2 PPG)
Rubit snatched 3.6 offensive rebounds per game and will look to get even better when the Jags hit the court again this fall.
Andre Roberson is an animal on the boards.
Roberson has led the Buffs in rebounding both of his first two seasons in Boulder.
Last year, as a sophomore, the 6'7" PF led the Pac 12 in rebounding (11.1 RPG; No. 3 in the nation), of which he pulled down 111 offensive caroms.
Watch for Roberson to have a monster junior season for CU.
Look out, ACC, if Richard Howell, the conference's top returning rebounder (9.3 RPG), picks up where he left off at the end of last season.
Mark Gottfried is hoping to see the same kind of performance from Howell that he saw when NC State faced Georgetown in the round of 32 and Kansas in the 2012 Sweet 16.
Howell grabbed six offensive rebounds against the Hoyas and nine offensive rebounds (16 total rebounds) while facing Thomas Robinson and Jeff Withey.
Last year, Howell pulled down 135 offensive rebounds, good for No. 8 in the nation.
Even at 6'6", Chane Behanan is a force to be reckoned with on the offensive glass.
As a freshmen last year, Behanan gobbled up 117 offensive rebounds.
That's No. 2 among freshmen in the country behind Kentucky's all-everything forward Anthony Davis (119).
Because Rick Pitino loves hard-nosed, high-motor front-line players, Behanan fits right into the Cardinals' style of play.
Very few players fight harder for the ball than Fordham's Chris Gaston.
Gaston has led the Rams in scoring and rebounding all three of his years.
The 6'7" rising senior led the Atlantic 10 in overall rebounding last season (9.9 RPG) and averaged just under four offensive rebounds per game.
O.D. Anosike is a beast.
Anosike was the nation's leading rebounder in 2011-12 (12.5 RPG).
The 6'8" rising senior had 27 double-figure rebound games in 2011-12, with a high game of 22 boards against Fairfield.
Anosike is relentless on the offensive glass, pulling down 135 O-boards last year.
Louisville's Gorgui Dieng is absolutely coming into his own.
The 6'11" rising junior demonstrated in last year's NCAA Tournament why he will be one of the best bigs in the country in 2012-13.
Along with being one of the nation's best shot-blockers (3.2 BPG, No. 8 in the nation) Dieng grabbed 138 offensive rebounds last year (No. 6 in the country).
With both Behanan and Dieng attacking the glass, the Cardinals' opponents will have more than their hands full.
Jack Cooley is not the most naturally-skilled player in college basketball, but he uses every ounce of his size (6'9" 250 lbs) and energy to get things done on the offensive glass.
Because he plays with a great deal of intensity and high basketball IQ, he is always where the ball is.
Cooley faces athletic bigs every night in Big East play, but somehow manages to pull down four offensive rebounds per game.
