The Rangers were as bad as the The Tigers and they were able to attract big time free agents. If a team wants to spend money, the players will come. Some of it worked out for the Rangers and some of it didn't, but they are doing really well this year. Back in 2004, 2005, the Tigers were able to sign Rodriguez and Ordonez and that worked out great. If a team doesn't want to spend money, that is their business. As a fan, I don't care about team finances. It's not my problem.
Also, as a fan, I am not sure I even want a team with a core of free agents. I would rather see them build a home grown roster for the most part. If they want to do it that way, the players will be glad to take the money though.
