They preferred Napier's 200 foot game and pro experience in the WHA. Bossy was small, not at all physical, and played in the Q, which was considered vastly inferior to the OHA and WHL.
And let's face it. The Wickenheiser over Savard pick only looks bad in retrospect. At the time Wickenheoser was the consensus #1 pick. Savard went 3rd, not 2nd but had the Habs picked anyone else at #1 Wickenheiser would have gone 2nd and fans at the time would be vilifying the Habs for their stupidity and saying that the Jets had made the steal of a lifetime by having Wick fall into their laps.
