As a team who is trying to compete for a championship, I want two types of players: reliable/consistent players with weaknesses we can protect/conceal, and superstars. I don't have room on my roster for "top 15" type players. Guys like Groot, Oliver, and Knox all eat up too much of the cap for what they provide, and the same can be said for our approach of loading up on 2nd tier talent at WR.
Kincaid is firmly in the 2nd-tier player camp so far. He'll cost you almost as much as the 1st tier guys while giving you none of that upside. His camp will probably use McBride's deal as a comp, and the Bills will probably have to fight to keep it around Hock's deal of $16.5M a year. **** that. I can count the amount of great games he's had on one hand, and he's had zero truly dominating ones.
Let him go and pay a rookie 1M a year and/or sign Goedert for a couple year.
