Assuming that the workers are similarly skilled to how they were in DOTT, you're in a hell of a pickle. Assuming that the various contracts & obligations are similar, that complicates matters even further.
I'm impressed that you managed to wring a C- match out of Rocky in Dothan, that's more than I would have expected. I actually went back & looked at your starting roster, Dundee is almost certainly the best option you've got in that crowd at this point, the gap between him & the next best option seems very large.
I know what I'd do in this situation (I think) ... but a steady parade of loaners is a temporary fix at best, not to mention one that carries risk of bad chemistry. Better you than me buddy, better you than me
