10 worst
11 Jim Jeffcoat 1983 - Good, solid player. The only first round success story between Tony Dorsett and Michael Irvin. Had more than 100 sacks. Contributed to 2 SB teams. Also, never made even a Pro Bowl. Also, was in the most talent-rich draft in NFL history. Also, was taken 4 spots before Dan Marino and 5 before Darrell Green.
10. Marcus Spears 2005 - Solid enough starter. Aaron Rodgers was still on the board.
Not the worst player, but among the worst picks for that reason.
9. David LaFleur, 1998 - Supposedly the Cowboys rated him over Tony Gonzalez. Yikes. A good to dominant blocker, and valuable along the goal line blocking and receiving. So I don't think he was awful. But he didn't last long, either.
8. Danny Noonan, 1987 - Not a total bust. But with the 12 pick, you should be able to do better than Danny Noonan. Not a great draft, but not bad, either.
7. Morris Claiborne 2012 - Had a good year or two with the Cowboys. But was spotty and beatable. Traded a second round pick to move up to get him. The Cowboys' only true top 10 bust ever.
6. Taco Charlton 2017 - Since Claiborne, the Cowboys are on a solid run of first-rounders - Frederick, Elliot, Martin, Byron Jones, LVE, Lamb. And then: Taco happened.
5. Dennis Homan, 1968 - Probably the first Cowboys can't-play first round pick. Brief career.
4. Charley Young, 1974 - The Cowboys wanted Lynn Swann, chosen by Pittsburgh one pick before. The Cowboys settled for Charley Young, who couldn't beat out all those no-names that forced us to trade up for Dorsett.
3. Bobby Carpenter 2006 - Had a bad habit of being waived quickly by any team who picked him up. The next two selections were Pro Bowl players. Wasn't an end-of-the-round pick, either.
2. Scott Appleton, 1964 - The Cowboys drafted Appleton at #4 in the 1964 draft as part of a trade with Pittsburgh for WR Buddy Dial, who was coming off 3 1,000 yard seasons. Both guys ended up sucking thereafter. Appleton became a journeyman. Dial went to the bench quickly. Brandt has said the Cowboys were considering Paul Warfield in that draft. Carl Eller was drafted 2 picks later.
1. Rod Hill. 1983 - Of the notorious group of Cowboys first-round busts from 1978 to 1987, most were injury cases (Shaw, Cannon, Sherrard) or JAGs (Richards, Bethea, Brooks). Only one of them couldn't play at NFL level at all. That was Rod Hill.
