Saints lack of interest in prospects in their range at 14?

My question is why do the saints seem to lack interest in terms of visits or contacts for the following?

Oil Fashanu
Troy Fautanu
Taliese Fuaga
JC Latham
Jared Verse

On the other hand they have met/seen:

Byron Murphy
Chop Robinson
Cooper Dejean
Johnny Newton
Brian Thomas Jr

Am I reading too much into this or does it seem they’re more interested in guys going in the late teens/early 20s? Why the lack of interest in bringing in any of the OTs?
