So this is how I see the Laba deal and most of this has been suggested already in it's various parts which is good to see... (I hate looking totally insane, at least not without wearing a straight jacket or clown make-up)
So Dike injury happens. Laba has to be loaned to make the team rule compliant. We can't score because Weids (I'm sorry) is only slight more useful then Mista.
We need more power up front, but the salary cap is an issue, a Loan out of Laba and keeping part of his salary may be a hindrance to bringing in a Number 3 striker. So the loan becomes a Trade and we dump the whole salary.
The Future considerations maybe the ability to do a net zero trade of Laba back to TFC in a year or Allocation if we needed it to bring in a 3rd striker.
getting the "most" for Laba may be the full salary dumb to replace Dike
