Whether it's due to lack of size, playing at a smaller school, a small playing sample size, injury history, maturity issues or a poor performance at the NFL combine, some draftees drop or are ignored because of a teams' wariness to select them.
Sometimes, teams out-think themselves focusing not only on a player's production on the field, but rather on other factors.
When teams do this sometimes, these questionable picks come back to bite them in their rear.
After setting all kinds of NCAA receiving records, Jerry Rice ran a 4.7 40 at the combine. His lack of speed and the fact that he went to Mississippi Valley State University, a small school, led him to drop to the No. 16 pick. He was the third receiver taken, behind Al Toon and Eddie Brown. Both had respectable careers but nowhere near Rice's.
Even though Tom Brady won 20 out of 25 games as a starter at Michigan, along with two bowl game wins and was an All Big Ten honorable mention, his horrible combine performance and measurements dropped him to the sixth round even.
Former Defensive Player of the Year James Harrison went undrafted after teams feared his lack of size. Going into the 2002 NFL draft, Harrison only measured at 6'0'' and 240 lbs.
Most recently, after being named a two time All-American at Central Michigan and catching 110 balls in his junior year, the undersized 5'10'' Antonio Brown dropped into the sixth round before the Pittsburgh Steelers drafted him with the 195th-overall pick in the 2010 draft.
Since then, he already has been named to his first Pro Bowl.
Every year, a player drops. Here are players in this year's draft that are worth taking a chance on.
