i think there is no chance that the league and its owners would have let a first year team get a franchise player like that. remember that in '93, the league wouldn't let the two expansion teams have any of the top three picks (because daigle, pronger, and gratton were supposed to be franchise-altering players).
but had he gone to the sharks, things could have been interesting. for one, they never would have drafted ray whitney if they hadn't already taken his junior linemate pat falloon second overall. would that second round pick have been ziggy palffy? lindros, palffy, and ozolinsh is a pretty awesome base to start a team-- they all became impact players much earlier than whitney did.
if lindros had given the sharks the privilege of having him play for them (yes, i'm being sarcastic), the '91 calder race becomes more interesting for sure. bure had a very good rookie year, but there is no way he wins in either '91 or '93 so it was a weaker calder for that era.
if lindros for whatever reason decides he won't play for san jose, that would probably have been more beneficial for the sharks hockey-wise, though not necessarily financially. all those picks (and the sharks were a pretty good drafting team), very good young players, and a ready to go starting goalie. they would have gotten that package no matter where they traded him.
as for lindros' career, i feel like he was tailor-made to play in that division, to go against big centers in messier, sundin, holik, and mario. in the more free-wheeling west, maybe what happened to thornton happens to lindros and he becomes more of a finesse guy than the force of nature he was in philly. i certainly think he would have lasted longer out there, but maybe he also would have been a less special player. or, on the other hand, maybe he eats the less physical smythe division for lunch and wins multiple MVPs.
maybe the more interesting question is what happens to the nords/avs with niedermayer but no forsberg, thibault/roy, hextall/deadmarsh, ricci/tanguay, duchesne, and simon. for one, it's almost a certainty they never trade sundin for clark, and so they don't get claude lemieux. could they still somehow get roy?
