Unhappy with those 4 players over someone else or just unhappy with them? In either case, my drafting strategy that you don't like is fine as long as there will be, in your opinion, players you like available at #13 that you don't think are reaches. I don't think it's my strategy you don't like, I think it's the players I want that you don't like.
Unhappy with them at #13. Don't rate them that highly.
I'd say it's a bit of both...although I'm sure the players heavily influence the strategy...so the probably the players since they're likely the cause.
In any case, I'm in no way painting myself into a corner because I have plenty of options that I like that will be available. None of which would be a reach IMO. I call it having an overall plan. Without knowing the details of what you want to achieve out of this draft, I'd say that you don't seem to have an overall plan and seem to want to pick BPA regardless of need. That might work but it's not a strategy I would use with a team that is close to being a contender if not for having some major holes holding it back.
I have a "plan". It's my board. I work from that. You give me the pick number, the players available, and any trade options(if there are any)...and I can tell you exactly what I do in that situation. You change the parameters of that situation, I can immediately tell you what I'd do with the different parameters. It's definitely planned. It's why I spend so much time on this type of stuff...so I know exactly who/what I want come draft day.
I just don't prefer to specify what positions I am going to address where. I let the draft dictate that because you can't control who other teams pick.
And I definitely don't ignore need. I just don't let it dictate where I pick players. It's something I take into account when making my "board".
