I doubt it.
Kraft's Net Worth, depending on the source, is somewhere between $11b and $14b. The Pats have Cap Space of around $54 million, which is the highest reported in the NFL but less than one half of one percent of Kraft's worth, i.e., probably a rounding error in his Cash Flow.
Kraft's track record suggests that he understands how to build a winning franchise (unlike Woody Johnson, for example).
So, I'm pretty sure that rationing Cap Space is a strategic decision rather than a financial decision as they rebuild over the next couple of seasons: 2025/26 will give them an idea of what they need to plug. The good news is that it looks like Drake Maye could be "the guy," so that would free up a lot of cash to bolster the rest of the roster. But anyone who thinks that was a "given" until this season was kidding themselves. The Mayo-error cost them at least two years of rebuilding, which I wrote out here within a day or so of when he was named HC. That was a mistake that is on the Krafts...and a big one, but doesn't define who they are.
BTW, contrast the above with the Bills, who have only $3million of Cap Space and a roster with the oldest average age in the NFL. They were built to win around Allen, but haven't even gotten to the SB yet.
