The 2011 NBA Draft has proven to be one of the deepest classes in recent memory.

The draft was so deep that 29 teams missed one of the best prospects — Isaiah Thomas.

The Kings took Thomas with the very last pick, No. 60, completely unaware that the diminutive 5-foot-9 guard from Washington would become this generation's Allen Iverson — a spunky, athletic, crafty scorer defenses can't stop.

After stops in Sacramento and Phoenix, Thomas has become the star of the Celtics, helping them win the No. 1 seed in the East this year.

Here are some of the players drafted before Thomas that NBA teams are probably kicking themselves over today.
