I will say that there have been many times that I’ve pretty much made up my mind (95%) on a major purchase, but I continued to check out a couple of other options, just in case. I’m sure the business managers of the stores that were mostly out of the picture, would have not been happy if their people hadn’t at least made an effort to change my mind.
In my business, I have also continued to interview candidates for a few days, even after I’ve been 95% sure I had already found the one I’m looking for. There have been a couple of times that I’ve been very glad I turned over a couple extra stones and not settled. Pretty sure that people have interviewed with me, knowing that they weren’t going to take the job, but just wanted to take a closer look, to be sure. I don't blame them for doing that. I'll bet a lot of us have done that in our career. Did you blame the guy interviewing you for not being able to blow your preferred option out of the water?
Although it seems like a waste to put in time on something that is likely not going to happen, (and I completely respect and understand that thought process-concentrate your efforts on what you CAN get, not what you CAN’T get) but I also can imagine the criticism that would have come to coach Johnson for not at least trying, (can’t win if you never try) to get a commitment from some of the possibilities that may have already 95% made up their minds to do something else. if I'm not mistaken, I have seen that exact criticism from some posters over the years about that exact situation. There seems to be a lot of “Dammed if you do and dammed if you don’t” from the variety of sports fans we have here.
