This selection is on Jerry Jones, as he reached by at least one entire round, or maybe more. However, Carter's downfall was on himself.
Carter was picked in the second round of the 2001 NFL Draft out of Georgia, and was made the starter in his rookie season after Troy Aikman retired.
The Cowboys finished 5-11 and deal last in the NFC East. The highlight of Carter's season was a 20-13 win over the Giants in which he threw for 200 yards. He was replaced by Chad Hutchinson in 2002 and the Cowboys finished dead last again.
When Bill Parcells took over the team, Carter was again named the starting QB and played well, leading the Cowboys to a 10-6 record and a wild card playoff berth. However, during training camp the next season Carter was released after a failed drug test.
Parcells said that Carter's release was due to, but not limited to, his drug problems. He landed with the Jets and started three games but was also cut by them after the 2005 season. Since then, Carter has been arrested at least three more times on possession charges, and was once bailed out by Cowboys beat writer Randy Galloway.
The reason Carter is at the top of this list is because of how much his personal problems derailed his career. He provided fans hope that he would help lead the Cowboys back to the glory days (after the 2003 season), but his drug issues prevented that from happening.
Because Carter was cut from the Cowboys, Tony Romo stayed with the team and eventually worked his way into the starting job. The Butterfly Effect at its full impact.
