I wouldn't do it.
- Five 1st rounders would cost a fortune to sign.
- Out of five 1st rounders, two would be busts. High-paid busts.
- Out of the three non-busts, only one would become a true "impact player", but still probably not the level of impact of a monster like DeMarcus Ware.
- The other two non-busts would become solid starters.
So you'd be paying five guys 1st round money AND losing the best pass rusher in the game (and one of the best all-time) in his prime... in exchange for 1 impact player, 2 solid starters, and 2 busts.
Only way I'd do this is if the Cowboys were in rebuilding mode. But the way our roster looks now... no way.
