I certainly never said that Jackson was the answer, and I think many others have had reservations.
The problem is where are we going to find someone now? As I pointed out in a pvs. thread, other trade options earlier this year didn't pan out to much (Lynch, Barber, Williams (hurt)).
You're rarely going to find a season-changing RB (or any starter) at this point in the season and to BJack's defense, esp. in the 1st Q he was hit in the backfield an awful lot.
