Prior to the 2009 NFL Draft, nobody was climbing the first-round ladder faster than LSU defensive end Tyson Jackson.
When the Kansas City Chiefs were on the clock, Scott Pioli decided to pull the trigger on Jackson and made him the No. 3 overall pick.
Conversely, Southern Cal linebacker Rey Maualuga was regarded as a solid selection in the middle of the first round of that same '09 draft.
By the time Maualuga's free fall was over, he had slipped all the way down to No. 38 overall and the Cincinnati Bengals.
Each and every year, in the NFL Draft, we see guys make big sweeping moves up and down draft boards in the final hours.
Teams get panicky that they won't "get their guy," and become willing to reach or trade up to secure the player they covet. Meanwhile, other teams nitpick and obsess over certain elements (size, 40-time, motor, etc.) of college players' games, and those guys begin to slide uncontrollably once the selection meetings begin.
Tyson Jackson and Rey Maualuga are merely two examples of this, and it still remains to be seen how their respective careers will play out.
One thing is for sure, though, we will see more last-minute surprises in New York City tonight at Radio City Music Hall.
