It's bad faith to equate playoff race and actual playoffs.
No matter how many times a team is in the mix, unless they get a taste of the actual thing, they will have no playoff experience when they finally are in the playoffs, and that matters.
Furthermore, being in the race only to repeatedly fall short sets the precedent of a losing culture.
A pick in the 10-16 range is not super valuable, as the hit rate is not great and the lottery odds are near zero. Franchise-saving talent is rarely drafted in that range. The consolation prize is not worth more than a playoff ticket.
The problem with Detroit is precisely that they lack franchise players. They have a good group of solid youngsters, but not one of them is really elite in my opinion, and I think many would agree. Which is to say that even if that young core learns along the way to a 14th overall pick, their upside as a group is not a cup contender, so it doesn't really matter.
What they really need is a top 5 pick, or at least to hit a homerun elsewhere in the draft. But their drafting philosophy has leaned towards high-floor players rather than homerun swings, as if they had the elite players already and needed depth pieces to round out the roster. We'll see how the cards fall in a few years. My bet is stagnation.
