I think Ambrosie did it to curry favour with Bettman so they can have another outdoor game at a CFL venue, which will of course save the CFL with a massive payday and make Randy Bo Bandy the greatest CFL commish evah and Bettman some sort of Canadian football folk hero. This in turn will enrage Wade Miller, who no doubt has CFL commissioner aspirations, and he'll take it out on Walters and O'Shea, effectively ending the Canadian Mafia, much to the delight of Dave Dickenson. /s
In all seriousness, though, it was just pure chance the Rangers got the first overall pick. Of course it's a win for the league and a big market in the Big Apple but I don't think any shenanigans were afoot.
As for the Jets, taking a defenseman or a centre at 10th overall seems like a no brainer. Sanderson or Guhle would be nice adds on the blue line; Perfetti, Lundell, or Mercer would be nice adds down the middle.
