A few don't have enough list spots for the number of decent picks they have. A few others have more spots than their number of decent (sub-70?) picks in hand. Rough guesses based on this info - note that it doesn't take into account OOCs like Barlow:

Adelaide: 0 to delist (4 spots; can use 13, 43, 53, 67; not 89 etc)
Brisbane: 0 to delist (5 spots; can use 3, 16, 21, 22, 76; not 78 etc) (maybe 1 to sign/promote?)
Carlton: 0-3 to delist (3 spots; can use 5, 25, 48; not 63, 66, 70, 81 etc)
Collingwood: 0 to delist (6 spots; can use 28, 44, 51, 62, 65, 83) (maybe 1 to sign/promote?)
Essendon: 0-1 to delist (4 spots; can use 1, 20, 29, 41; not 68 etc)
Fremantle: 0 to delist (4 spots; can use 7, 35, 40, 71; not 79 etc) (maybe 1 to sign/promote?)
Geelong: 0 to delist (6 spots; can use 24, 38, 42, 64, 72, 74; not 91 etc) (maybe 1-2 to sign/promote?) (went with 38 this year)
Gold Coast: 2 to delist (2 spots; can use 4, 6; not 8, 10, 73 etc)
GWS: 0-4 to delist (7 spots; can use 2, 15, 37, 39, 45, 52, 55; not 57, 58, 59, 60, 77, etc)
Hawthorn: 2 to delist (1 spot; can use 88, 90, etc etc)
Melbourne: 0 to delist (3 spots; can use 47, 69, 84) (maybe 1 to promote?)
North Melbourne: 0 to delist (4 spots; can use 11, 32, 33, 87; not 92 etc) (maybe 1 to sign/promote?)
Port Adelaide: 0 to delist (5 spots; can use 14, 17, 30, 31, 85) (maybe 1 to sign/promote?)
Richmond: 0 to delist (3 spots; can use 27, 56, 82) (maybe 1 to promote?)
St Kilda: 4 to delist (-1 spots; can't use 23, 36, 61, 86, etc)
Sydney: 0 to delist (7 spots; can use 9, 19, 46, 49, 93) (maybe 1 to promote?) (usually go with 38)
West Coast: 0 to delist (3 spots; can use 12, 34, 54)
Western Bulldogs: 1 to delist (2 spots; can use 18, 26; can't use 50, 75, 80, 94)
So based on that most likely 10-15 more to delist, and a few spots for another signing - though keep in mind that only 6 clubs went with 40 on the list this year, most had 38 or 39.
Thoughts on who might be still to go? Or get signed/promoted to fill list spots?
