Grier gets universally shat upon for "giving out contracts" and "screwing up the cap" when in fact Brandon Shore is the lead negotiator on all contracts and is responsible for salary cap management. Since the amount of the contract for Jonah ( and all drafted players) is predetermined ( 4 yrs. $11,310,028 with preset annual salaries) I would venture that Grier actually has no input on this or any draft pick signing. The UDFA's I would imagine Grier and McDaniel have way more input due to the smaller amounts of any contracts and/or how desirable the individual UDFA's are, but at the end of the day Shore is negotiating actual terms and how an individual contract will fit under the cap. As for free agents, past experience certainly has shown McDaniel and/or Grier have
had the ability to "pound the table", but it certainly appears , at least for 2025, that may not necessarily be the case going forward. Bio for Shore and link to rookie contract slotting below-
