I don't know the answer.
My gut feeling is that a player rated by the media as a top 20 type will drop to the Cowboys and they'll take that player regardless of position.
Both Forbes and McDonald are interesting in that they have larger wingspans than expected for "undersized" players.
- Forbes has a larger wingspan than 3 of the top 4 CBs.
- McDonald has the very long arms that Dan Quinn loves (34-7/8").
McDonald's weight (240) is not that far outside other early NFL draft picks at his position.
- Randy Gregory 235
- Micah Parson 246
- TJ Watt 252
Have there been any 1st/2nd round CBs that weighed 170 (166 at the combine) ?
Darrell Green's NFL listing is 5-9, 184.
Pacman 5'9-1/2", 187 (combine).
Nahshon Wright was only 183, despite being 6-4.
- He also has a smaller wingspan than Forbes (77-7/8 vs 79).
