be squirreled

''Many of the mistakes that the affirmative teams make when setting up debates are also the perfect weapons for negative teams to use - especially if they are squirreled or have limited knowledge of the substantive issues in a debate."
what does ‘they are squirreled’ mean here, please?

My only guess is it can imply ‘the squirrel grip’ that is, from slang into English, when you have your opponent helpless and in an awkward situation. The affirmative team propose a plan, the negative ream try their best to get their opponents cornered by questioning its reliability.
You know the rest.
