Well if we took 7 OL next draft the law of averages would have us get at least two that were good. As long as one is a tackle we would be OK.
Desperate situations call for desperate measures.
Unfortunately, it doesn't really work that way. Just as an example, take last years draft, when there were 33 offensive linemen taken. In the first three rounds there were 6, 6, and 7 OL taken. Let's assume that 33% of them will turn into quality starters. For rounds 4 and 5 there were 5 and 8 players taken and we'll set the success rate at 20%. Then, for rounds 6 and 7 there were 3 and 8 players taken and we'll put the success rate at 10%.
To make things easy, we'll pretend like Dallas was picking at #20 in every round.
Last year, 3 OL were picked before the 20th spot. To reach our 33% success rate, only 6 OL have to be taken. That means that there is a chance that half of the quality starters between rounds 1-3 have already be taken by the time Dallas picks in the first round. Let's say that one of those first three guys is a bust, that means there are 4 more quality starters in the next 13 players taken. The odds are 70%
against us choosing a starting quality player at pick #20.
By the time our pick in the 2nd round comes, there have been 5 more OL taken. So, from our original pool or 19 "33%" players, there are 10 left. Now we'll assume that another two of the quality starters was picked up, either by us or someone else. That leaves 2 left and now we face '4 to 1' odds against us.
By the time our 3rd pick comes around, another 7 OL have been taken and there's no more 33% success rate players left in the pool. If we want to keep drafting OL, then we have to dip into the 20% success rate club, which makes our pick a reach. Even taking the first player from that pool, we face the same 4-1 odds that we did in round 2.
I ran these odds through a random selector 10 times, these were the results.
1: Bust, Bust, Bust
2:
Success, Bust, Bust
3: Bust, Bust, Bust
4: Bust, Bust,
Success
5:
Success, Bust, Bust
6:
Success, Bust,
Success
7: Bust, Bust, Bust
8: Bust, Bust, Bust
9: Bust,
Success, Bust
10: Bust, Bust, Bust
In 5 of the 10 trials, we don't hit on
any of our first 3 picks, nearly half of our draft is wasted. In 4 of the 10 trials, we land 1 starting quality player, that means that the odds are against us choosing a starter. Only in 1 of the trials do we reap any benefit from the 'draft all OL' strategy.
The final rounds look something like this...
1: Bust, Bust, Bust, Bust
2:
Success, Bust, Bust, Bust
3: Bust, Bust, Bust, Bust
4: Bust, Bust, Bust, Bust
5: Bust, Bust, Bust, Bust
6:
Success, Bust, Bust, Bust
7:
Success, Bust, Bust, Bust
8:
Success, Bust, Bust, Bust
9: Bust,
Success, Bust,
Success
10: Bust, Bust, Bust, Bust
So, in the ten trials, we come out with 1 or fewer starters 70% of the time, even though we spent all 7 picks on OL.
The odds of finding one starter is 40%, just 7% higher than if we only chose an OL in the first round. The odds of missing on all the OL picks is 30%, a full 37 percentage points higher than if we only took one in the first round. The odds of finding multiple starters increase from 10% to 30%, which still isn't a number that you'd want to gamble your draft on.
