While that may not been what he was referring to I don't think that is too unlikely.
Jets will either be going with Bridgewater, McCown, or breaking in a rookie QB on a roster that has quite a few needs.
To be in the top 50 the Jets just have be in spot 18 or higher.
Essentially the question is, with all of those things being true of the Jets, do you think they are likely to be an above average team next year or do you think they are likely to be an average or below average team?
The #18 team this year won 9 games. Even if the Jets pick their QB well, winning 9 games, especially when they have to play the Pats twice a year is going to be tough.
