I think the big problem here is a few things working against each other.
-Arte does not like to do a full rebuild
-Arte likes to sign big names at their high point (and right after)
-Arte will spend yes, but he is cautious. He clearly wants to stay below the luxury tax.
The result of these 3 things is we always hover around mediocrity because we take on big contracts by players who under perform , but won’t bust the budget to be competitive.
