I think there's a trade missing regarding Eric Vail.
16-Jun-72
To The Atlanta Flames - Lynn Powis, Rey Comeau
To The Montreal Canadiens – 1973 2nd Round selection (Eric Vail) and Cash
10-Nov-81
To The Calgary Flames - Gary McAdam, 1982 4th Round selection (Dave
Meszaros) and 1983 4th Round selection (John Bekkers)
To The Detroit Red Wings - Eric Vail
The Flames traded Vail twice without acquiring him in between.
On a Canadiens website I found this:
http://www.habswatch.com/p/trade-his...l#.W3U5--gzY-U
May 15, 1973 - 1st round pick #2 (Tom Lysiak) in 1973, acquired from California Seals, 1st round pick #16 (Vic Mercredi) in 1973 and a 2nd round pick #21 (Eric Vail) in 1973 traded to Atlanta Flames for a 1st round pick (?) in 1973, later traded to ? for a 1st round pick #10 (Mark Napier) in 1977 and a 2nd round #30 pick (Dale Yakiwchuk) in 1978
Hockey DB has Vail as being originally drafted by Atlanta.

which would mean Atlanta already drafted him before they made the trade with Montreal and that would make the first Vail trade look like this:
16-Jun-72
To The Atlanta Flames - Lynn Powis, Rey Comeau
To The Montreal Canadiens –
1973 2nd Round selection Eric Vail and Cash
(Correct me if I'm wrong ofcourse)
