Maybe he does.
Here is a former front office executives view after the extension to Kyler Murray:
"Cardinals owner Michael Bidwill also likely hid behind the antiquated NFL funding rule by arguing that, unlike Browns owner and tycoon Jimmy Haslam, his family did not have the resources to put $170 million into escrow."
Here is the view from an agent:
"A fully guaranteed contract never seemed like a realistic possibility for Murray because the Cardinals aren't considered a cash-rich team. Meeting the NFL's archaic funding rules, where teams are required to put into an escrow account the amount of any guarantees in a contract other than those just for injury, including ones in future contract years, was going to problematic for the Cardinals."
Here is the view from a journalist:
"For Watson, Browns owner Jimmy Haslam must deposit $169 million into an escrow account by March 31, 2023. As one source recently explained it to PFT, that’s quite possibly a check that Cardinals owner Michael Bidwill can’t afford to write."
Again, I am not saying it is a big problem, but it is certainly a bigger potential risk than most fans know about.
