I think it depends on how much the ownership is willing to spend. That is probably determined by how much they see they have made and are making by winning.
I could see it happening this way:
Maggette takes the full MLE.
With Pollard, House & TAllen off the books that's about $5mil. So if we then match a Posey offer sheet for $6 mil a year we are not that much futher in the hole financially...fill in the other two spots with lle and/or Vet min contracts...
It's possible.
But we can't do that. Simply put, the league wouldn't allow it.
We have 5.8 Million we can spend on one or a combination of players
We have 1.91 Million we can spend on one player
We can sign any player to the vet minimum
If we had extended a qualifying offer to TA, we could have retained him without affecting our MLE or LLE, but resigning posey or house would absolutely require the MLE and/or LLE in the case of House.
While
whether or not we use the MLE and LLE to sign players is the owner's prerogative, how much total we have to spend on players is not. Thats mandated by the league, and its the same for every team over the salary cap. This is completely unrelated to the luxury tax.
