I do not see a way to avoid Detroit sliding into mediocrity in the last decade, and certainly no solution to make the team a legitimate contender. I'd instead focus on giving Detroit the best chance to win the Stanley Cup while doing something somewhat realistic.
Draft either Vlasic or Letang in 2005 rather than Kindl.
Detroit's best chances by far to win Stanley Cups, other than the one it did win in this window, are 2007 and especially 2009. So, I'd want a player who can contribute to winning those Stanley Cups on a cheap contract. Vlasic played top pairing minutes for a solid San Jose team as early as 2007 and was a quality number 2 by 2009. I don't know that he really makes a difference in 2007, but I'd be content to give some of the Lilja/Lebda minutes to Vlasic instead. That's even more true by 2009, when he very well could tip the balance.
Letang is more of a stretch as the pick in that he was a third rounder, but it wouldn't be a total reach at the time. It's somewhat cheap to steal him from Pittsburgh in 2009 but Letang was ready to contribute by that year, so taking him over Kindl helps in 2009. Letang has no impact in 2007. Letang does more to extend Detroit's window beyond 2009, but Vlasic helps a lot and I don't see Detroit getting past the top teams in the West after 2009 even with Vlasic/Letang.
