Every Major League Sport can recount horror stories of players surrounded with giant expectations picked early in an entry draft only to fizzle out in a few seasons.
The Detroit Pistons selected 7'0" center/power forward Darko Milicic behind Lebron James and before some people you might have heard of: Carmelo Anthony, Chris Bosh and Dwayne Wade. He now comes off the bench for the Minnesota Timberwolves.
The Oakland Raiders used the first overall pick in the 2007 NFL draft to take JaMarcus Russell out of LSU. A 65.3 passer rating and three disappointing seasons later, Russell is looking for an NFL contract.
It's hard to say if any players in this year's NFL draft will join the ranks of biggest busts of all time, but several players expected to be taken in the first round already have naysayers to prove wrong.
Ryan Tannehill, selected by the Miami Dolphins with the eighth overall pick, completed just over 60 percent of his passes in two seasons at Texas A&M. He finished last season with 29 touchdowns and 15 interceptions.
However, Tannehill started only 19 games in his career at Texas A&M. Much of his high draft projection is based solely on potential. While he might be a formidable NFL quarterback one day, he is not ready to start for the Dolphins and probably not worth a first-round pick.
Tannehill was projected as a fourth-round pick before the start of the season. His draft stock rose so dramatically simply because there aren't a whole lot of starting quarterback candidates after Andrew Luck and Robert Griffin III.
His size and the potential are there, but the Dolphins simply can't expect him to start as a rookie and turn around their 6-10 record from last season.
That being said, Tannehill isn't alone in his quest for potential bustdom.
