I have actually been getting on to this topic on my own time, and starting to cover some of my thoughts in my articles over the last two weeks (plus another one out tomorrow). You can find those through the link in my signature.
Kane is covered in the articles, so here's projections on the rest from my prediction model (still a big work in progress):
Nurse - $4,120,753 x 4yrs
Bjorkstrand - $3,141,824 x 3yrs
Ritchie - $2,645,243 x 3yrs
Lindholm - $4,396,003 x 4yrs
So all similar range. I would expect $4M to be the minimum for Nurse, and Lindholm I see locking in a longer term deal after already having done the bridge deal. I would bump his projection up to $4.75 x 5yrs.
