The Dodgers model is one that mid market teams will not be able to compete with long term. That is why the CBA is so important for the owners to get on the same page about revenue sharing, tv deals, etc. The luxury tax just isn't a significant hurdle for large market teams, because they can overcome the luxury tax with all the revenue they generate from TV, merchandising, and ticket revenue.
As for the money we offloaded, we could have elected to not offload that money, but what kind of return would we have received? When you are rebuilding, you need quantity and quality in return for your aging stars.
As for the Donovan situation, with Bichette seemingly off the board to a team that wasn't even in the reported Donovan suitors list (Mariners, Giants, Red Sox), it makes me think that the bidding war is going to be there. I could see Bloom waiting on this one a bit, because the spots for the young guys are open either way now. Teams are going to get more and more desperate the closer we get to Spring Training.
That being said, if we don't hear the return we want, I would like to see the Cards extend Donovan on a 4 or 5 year deal. That still gives us the flexibility to trade him before the trade deadline or we could decide to make Donovan our veteran holdover that leads us to the next era of winning baseball.
