Could Ozzie shift back to short, leaving Grissom at second? Or is the arm too much of a concern? This is a question; not a suggestion. I literally don't know the answer.
Of course, I am firmly on the resign Dansby train.
I don't personally think Ozzie can go back to SS - the loop in his throwing motion seems like it would be too much to overcome.
That said, I don't understand why re-signing Dansby is such an issue - he's good (without question), and one of those "glue guys" that us old school fans (and our booth geniuses) have typically always overvalued. They have all sorts of ways to replace him WITHOUT spending $100 million plus. If Alex chooses to bring him back I'm more than fine with that, but if he decides to spend that money elsewhere he's already proven that he's the person that needs to be making that call - he proved he could let a much better player than Dansby walk last winter and knew EXACTLY what to do so the clubhouse and chemistry didn't crumble.
1.) Sign Iglesias or Diaz and make Grissom the RH part (at the very least) of the LF answer and your super-sub.
2.) If Alex is told he can't eat Ozuna's money, he may still be able to eat Rosario's - go get Benintendi (can handle both corners), make Grissom your super-sub, and sign Iglesias/Diaz as your defensive SS.
3.) If he can't eat Ozuna's money, offer Nimmo or Naquin (both can handle either corner as well as back Harris up in CF) a nice deal and have one of them in LF with Grissom as your super-sub and sign Iglesias/Diaz as your defensive SS.
4.) Re-sign Grossman since he can handle both corners so he can split time with Grissom in LF and sign Iglesias/Diaz as your defensive SS.
5.) Sign Conforto (can handle both corners) and one of Iglesias/Diaz as your defensive SS, make Grissom your super-sub if you're going to spend big.
I just think the money can be spent in a variety of more productive ways - even if Alex doesn't spend the whole amount. Go see if you can sign one of Fried/Wright/Strider/Soroka to a reasonable extension with some of that money, spend some of it with one of the moves listed above, and keep some in reserve to replace Jansen or in case you need to make a move or two at the deadline. All of those moves listed above would allow you to use Acuna as a DH to get him off his feet ANYTIME he needs that. I personally want no part of Haniger despite his upside - he hits from the wrong side, and you've already got a ton of money tied up in a RH power hitter that strikes out a ton and kills rallies when he's not "on" (Ozuna).
