tanking rarely works.
mahomes and brady are some of the best qbs since 2000 and they weren't chosen first in the draft.
Why do Cowboy fans on this board think trading down is better than staying at your high pick?
But more to the point. How many other championship quarterbacks were selected out of the first two rounds versus the last four rounds? Your citing Mahomes and Brady leaves a great dal out of this discussion.
I certainly cannot speak to the mental intent of the Landry last year, per coaches and or management. But if we see that as a tanking year, since there were some of us fans who were more in favor of not winning for the 1st over-all, than winning a meaningless game or two, I'd say Troy Aikman kind of makes your point no point at all.
Plus, in that draft, since it is more than just one player, Dallas took Steve Wisniewski (guard) in the second, who played 13 years for the Raiders. In return they received compensation which brought Dallas Daryl Johnston and Rhondy Weston. Weston had a poor showing in training camp and was cut and picked up by Tampa Bay.
That draft also produced for Dallas Mark Stepnoski and Tony Tolbert.
Since draft slotting for a team is in all rounds of that draft and not just the first Dallas received:
Troy Aikman
Daryl Johnston
Mark Stepnoski
Tony Tolbert
So it is more than just the first pick you are tanking for.
