I hear Cowboys fans talk a lot about drafting the best player available. No team is successful drafting the best player available (BPA). Ask the Detroit Lions who drafted Charles Rodgers, Roy Williams, Mike Williams, and Calvin Johnson in almost consecutive drafts.
You draft the best available player of need (BAPON), ranking the players by grade, then by positions, ranking your needs in priority (prioritized needs), and then you make your BAPON draft board. You can trade up or down using BAPON but you better stick with the board. The 2005 draft that is on ESPN2 today shows how it worked correctly. Parcells wanted to change to a 3-4 Defense and need players. To go to a 3-4 D you better have and outstanding pass rusher at OLB that can also drop in coverage when needed. You also need a DL that can hold up at the line of scrimage and then be able to rush the passer (275 to +300 pound DL).
The Cowboys had DL as there no.1 priority position of need in 2005, and no. 2 was OLB. When the Cowboys came to pick in the 1st round of the 2005 draft, they had a dilemma. Demarcus Ware was the BAPON on the draft board, but the no.1 priority position of need fit was Marcus Spears, DL, LSU from Southern Lab High in Baton Rouge, and Nick Saban Coached. Parcell's loved Ware saying he reminded him of a retired LB in FL (LT), however his no. 1 priority need was not the no.1 player on the draft board. So the Cowboys personnel department (Jeff Ireland, others) had to conveince him to stick to the board and draft Ware then hope that Spears fell to their 20 pick in the 1st round or they could trade up to snatch him. Parcells did not want to take the risk but he also knew about the Cowboys not sticking with the BAPON draft board leading the all the sorry Larry Lacewell drafts that he required Jerry Jones to fire for Parcells to Coach the Cowboys. So, the Cowboys stuck with the BAPON and drafted future Hall of Fame and Ring of Honor OLB Demarucs Ware. The remainder of the draft BAPON was used and the Cowboys went for 4-3 to 3-4 in one draft, creating a playoff/super bowl caliber defense that continued through the lousy coaching and coaching carousel of Son of Bum, and that Red Head clapping idiot who finally wasted what was drafted in 2005.
BAPON was the method used by Gil Brandt/Wooten during the Landry years (20 consecutive winning seasons) before Landry got more involved in personnel decisions in the mid/late 80's. BAPON was used masterfully by Jimmy Johnson/Ackles/Wooten to build the Cowboys Dynasty of the 90's. BAPON was totally neglected during the Jerry Jones/Lacewell years. BAPON was brought back during the Parcells years (see the trade down in 2004 that lead to the 2 1st round picks in 2005). Neglected again during the Jerry Jones/Tom Ciskowski years. After the 2013 fiasco (trade down not using BAPON) BAPON was brought back by Will McClay. However Jerry still can mess it up when he listens to coaches vs. scouts see the Hill DT pick, and the waste of former 1st round pick Taco Charlton, who had as many sacks as Demarcus Lawrence in less games last year for the Dolphins as Lawrence cost per sack total was $4M less than Taco.
When you draft the Best Available Player of Need according to your draft board, you will pass on Johnny Football, and draft a OG from Notre Dame named Zach Martin. Keep yourself and your coaches out of the selection process, and never draft the best available player without looking at prioritized needs or you will end up with 4 WR as your number one pick 4 out of 5 years.
