Assuming players in the same tier are equally as talented and you could select them in any order without having a visible drop in terms of talent, do you mean you would be willing to draft Bosa or VHIII at #1, if we had the pick? (in case they're both included in that top6, of course).
I personally wouldn't because I see quite a difference between Tunsil, Ramsey and the other 5, but I'm curious ;).
I also realized that using as thin tiers as possible also kind of helps me defining the epithets "reach/steal". Empirically, we don't have a formula that indicates when in the draft a player can be considered as such.
I see it this way: if a prospect is not selected for the entire lenght of the 2 tiers following the one I located him, I have a steal.
My tier1 and tier2 include the players we very well know in the order I previously mentioned; tier 3 goes between 8-11; t4 is 12-22; t5 23-34, t6 35-49. Tiers tend to get wider and wider as draft progresses as I don't have as many infos on the latter players, but we're still able to put them in distincted categories.
For instance if Sheldon Rankins, who's in my tier3, gets selected after #36 (where tier6 starts), I'd have a steal.
If we maintain the 2skipped tiers 'formula' for the reversed situation we'd have too many reaches. There I'd consider the lenght of one as enough (if Conklin, t4 is taken between 3-7, t2).
Of course, this is no perfect science, just a funny system I use to give a sense to one of the most abused words circulating in the post-draft days.
edit: I hope at least few of you were able to decode what I just wrote ;D
