I cant think of a team that has consistently topped the draft year in and year out. The Cowboys had it on lock when Jimmy Johnson was there. Not counting the obvious first round stars(Aikman, Smith, Maryland, Harper etc...) they got:
Larry Allen
Eric Williams,
Larry Brown(12th Rd)
Brock Marion(7th rd)
Darren Woodson
Steve Wisniewski
Darryl Johnston
Jimmy Smith
Leon Lett(7th rd)
That was in a span of about 4 years all those cats are pro bowlers and couple are shoe-ins for the hall of fame.
