The more I think about it, the less likely I think it is that Kadri, Frattin and Gardiner will make the team. Line combos aside and barring any trades, here are the 23 of the 29 remaining players I imagine will stick with the big club:
1. MacArthur
2. Grabovski
3. Kulemin
4. Kessel
5. Connolly
6. Lupul
7. Armstrong
8. Bozak
9. Boyce
10. Rosehill
11. Orr
12. Dupuis
13. Lombardi
14. Mike Brown
15. Phaneuf
16. Schenn
17. Aulie
18. Liles
19. Komisarek
20. Franson
21. Gunnarson
22. Reimer
23. Gustavsson
Of the 29 in camp, I think these guys will be Marlies for at least the start of the year:
Frattin
Kadri
Scrivens
Crabb
Lashoff
Gardiner
If Brown and Lombardi end up on IR to start the year, Kadri, Frattin or Gardiner would likely be sticking with the big club at least temporarily while a roster spot is open.
