I apologize if this is old terrritory I'm covering but wanted to ask about the idea that all rankings should be made in a vacuum, that they should all be based on what would happen in a startup draft.
For instance, Luck is ranked QB4 and Brees QB6. Yes, you likely get Brees for 3 good/great years and that's it vs. Luck's first two good, then 8 possibly very good years.
But while rostering Brees, you have 3 years to find another QB who could put up similar stats to Luck in the long run.
To be more concise, I'd rather take the Brees points now and work to find my next starter than overpay for Luck - and for those reasons - I believe Brees should be ranked higher.
This is not about Brees and Luck per say, just used them as an example of why rankings should not be made in a vacuum alone.
Thoughts?
The key difference is though, if you're willing to regard Luck's success as fact, there is nothing that can alter that, you have that value for as long as you want it. With the Brees scenario, you're dependent on not only your own ability to scout talent, but to acquire it at a reasonable price as well as hope that other teams don't have similar views of any of those players and go all out to get them. If you find someone you like in 2 years time, but his success is less definitive, you're potentially putting a lot of stock into that potential at that point, which can be driven up by other parties. In that case you're possibly paying the equivalent value to success that you would have paid for Luck initially.
Not to mention you're dependent on Brees longevity and success. If he only plays up to a decent standard for two more years say, you're going to end up cashing in and overpaying early to maintain a smooth transition between Brees and your next QB.
In the Luck scenario, you have other value at play as well - Another roster spot, another chance to hold onto a roughie you like because Luck's success is defined. You might spend 2 less roster spots on the QB position, as opposed to holding three lesser QB talents in addition to Brees in the hopes that one starts performing at an adequate level to make the process worth it.
EDIT - Sorry if that rambling doesn't make sense, I'm in a rush.
