Baker Mayfield hasn't hidden his frustration with the Tampa Bay Buccaneers after the two sides failed to reach an agreement on a contract extension. While some around the NFL understand where he's coming from, one longtime scout has a much different opinion.FOX Sports' Eric D. Williams spoke with league sources about the ongoing contract dispute, including a longtime NFL scout who evaluated Mayfield when he came out of Oklahoma. The scout didn't hold back when asked about Mayfield's feelings of being disrespected by Tampa Bay."Mayfield is being disrespected by the Bucs? What a crock," the scout told Williams. "He's lucky they saved his career. He's got a big ego and needs to get real. In the NFL, they only give you what you prove."It's certainly a harsh assessment considering what Mayfield has accomplished since arriving in Tampa Bay. He's helped the Buccaneers win the NFC South twice in his three seasons as the starter, including a 2024 campaign in which he threw for 4,500 yards and 41 touchdowns.There is another side to the argument. Tampa Bay lost seven of its final nine games last season and missed the playoffs for the first time since 2019. Mayfield has also thrown 27 interceptions over the past two seasons, the second-most in the NFL during that span behind only Geno Smith's 32.Not everyone Williams spoke with sided against Mayfield. An NFL contract negotiator said teams generally don't want an important player, especially their quarterback, believing the organization is "getting over on them."That's ultimately the divide Tampa Bay, and Mayfield haven't been able to close. Mayfield believes his three seasons with the Bucs have proven he's a franchise quarterback worth being paid accordingly. At least one longtime NFL evaluator believes he still has more to prove.This article originally appeared on Bucs Wire: NFL scout gives blunt thoughts on Baker Mayfield contract talks
