Reading between the lines of Alvin Kamara’s commitment to the Saints

Blame Buffalo for trading the pick.
They did pretty well with the picks they received (#27 and #91 in 2017, #22 the following year).

#27 Tre'Davious White
#91 traded away as part of a package for #37 Zay Jones
#149 received from above trade, traded as part of a package for #63 Dion Dawkins
#22 (2018) traded away as part of a package for #16 (2018) Tremaine Edmunds

Mahomes is worth more than all of those guys, but they got Josh Allen the next year, so I don't think they are complaining. Went from a franchise that went 20 years without a 10-win season to one that has had 10+ wins in the last five years. Definitely an example of cashing in after trading back.
