You are absolutely nuts.
There is no way that JnZ is transferring to NU to be a backup. He was the best big on an ACC (though admittedly weak) team. He is capable of putting up double doubles. He delivers what no one short of Olah can deliver on this roster which is an inside presence and defensive capability on the bigs. He is a 5th year center with a man's body, and suggesting Falzon will pass him is ridiculous. Oh, and Lambiotte was All-B1G so I don't know what you are talking about.
I would be wary of transfers who come to NU because they couldn't get time at their old school. So, pointing to kids like Michael Thompson and Bernard Cote (and even Jared Swopshire) is totally irrelevant here. That is not the case with JvZ. He was their best big, and leading rebounder, and best post defender. He's got 4 years playing in the ACC. He can't shoot outside of 5 feet, and will be Shaq-like for us at the line, but that's not what we need him for. He is a critical and missing piece for the team in our weakest area - boards and post defense. His impact will be very big for us.
He is going to get 25 minutes a game, starting at PF and spelling Olah at the 5, but his main minutes will come at the 4. As for Falzon, he probably will contribute, but I don't see him starting. Those kids going to Louisville, Arizona, UConn on the New England All-Prep team are most likely not going to start either. As it stands, I think you'll see Sanjay as the guy who suffers the most from the infusion of size and talent. He got minutes at the 4 because of his defense, but he was way undersized and played only because we did not have anyone else on the roster who could play in the post - he couldn't naturally either, but at least he was a physical defender. Compare him to JvZ and it's not a question who you play against the other team's PF. Law moves back to his natural 3 position, as will Sanjay. Sanjay will continue to get some minutes as a defensive stopper, but you generally like your 3 to be an offensive threat as well, which is his weakness. The real question for Falzon is whether and how many minutes he steals from a 3rd year Taphorn. If Falzon is physically ready, then perhaps he will be a serious contributor. If not, you probably go with a Taphorn who has reshaped his body with 3 years of college weightlifting and a Skelly who is going to be another year bigger as well.
BTW, Law started because we continued to have a serious hole at the 4. He was not a world beater this year, and on most NCAA caliber teams, he comes off the bench. He's a sophomore next year, and at his natural position, he will be much closer to an NCAA caliber starter. But, unlike the previous two years due to a completely defective roster at the 4, we do not need him or Sanjay to play at there next year. At all.
