For the question ‘How many draft picks last for four years in the NFL?”
Definition of a Four-Year Career (Based on Games Played): A full 17-game season × 4 seasons = 68 games.
Average Career Length by Draft Round
Round 1: 62.3 games → approx. 3.7 seasons
Round 2: 56.3 games → approx. 3.3 seasons
Round 3: 48.1 games → approx. 2.8 seasons
Round 4: 44.4 games → approx. 2.6 seasons
Round 5: 40.5 games → approx. 2.4 seasons
Round 6: 32.5 games → approx. 1.9 seasons
Round 7: 28.1 games → approx. 1.7 seasons
Only first-round picks approach the four-year mark on average, but even they fall slightly short of a full four 17-game seasons (62.3 < 68).
The vast majority of NFL draft picks do not reach the equivalent of four full seasons in games played. Therefore, the proportion of players with at least four seasons worth of games (~68+ games) is relatively small and concentrated among higher draft picks (typically 1st round, and rarely top 2–3 picks depending on longevity).
According to StatVault-based career data:
Most draft picks have careers shorter than four full 17-game seasons.
Only a small fraction of early-round picks (primarily first-round selections) play four or more seasons' worth of games in the NFL.
Precise totals by player are trackable in the StatVault/NCAA dataset spreadsheet, which lists career games per individual draft pick from 2012 to 2021.

Note that the Cards are at #9 going back to 1979. Top grades are only at ‘C’ showing how much of a gamble the draft is.
As to MO as our GM, the stats don’t lie and verify the complaints on this forum. According to another great website ‘Sticktothemodel’
Monti Ossenfort's NFL draft record, 2023-2025: 28 picks, 7 starters, 4 busts, -15.6 value per pick vs league -7.6. By position, best and worst, every pick.
sticktothemodel.com
From that data:
Monti Ossenfort’s draft success rate is 23% — meaning 7 of his 28 picks have become starters — which is well below the league average of 40% (that 40% is from the StatVault data---MO's tenure is pulling down that grade!).
According to Every Pick Graded, Ossenfort has made 28 draft picks since taking over the Cardinals in 2023. Of those:
7 picks have become starters (25% starter rate, league average 31%)
4 picks have been classified as busts (36% bust rate, league average 31%)
23% hit rate overall, compared to the NFL average of 40%
His Draft Value Added (DVA) per pick is -15.6, which is significantly worse than the league average of -7.6
This indicates that, on average, his picks have underperformed relative to their draft slot.
Positional breakdown:
Best: Wide receivers (+11.4 DVA/pick on 3 picks) and offensive linemen (+7.0 DVA/pick on 5 picks)
Worst: Defensive ends (-25.8 DVA/pick on 3 picks)
Example picks:
Best value: Denzel Burke (CB, R5, 2025) +31 DVA
Worst value: BJ Ojulari (DE, R2, 2023) -62 DVA
In short, Ossenfort’s Cardinals draft record shows a 23% hit rate and 7/28 starters, both below league norms, with notable struggles in certain positions like defensive end.
