Okay, let me explain this to those who don’t understand: By saying “we can, and we will”, and therefore making a promise to his impatient and massive fan base, Dubas gave leverage to Nylander. Now, if Dubas fails to sign Nylander, he is in a position where he lied to his fan base. By making that comment, Dubas created increased external motivation for him to sign Nylander. This gave leverage to Nylander.
For a very, very simple analogy, for the posters that don’t understand: Kyle Dubas and Brendan Shanahan are with a 5 year old child in a toy store. The child asks “Kyle, can you and Brendan buy me this super awesome toy?” Dumbass Dubas responds “We can, and we will.” Then, Kyle asks the owner of the store how much the toy costs. Before hearing that comment, the owner of the toy store was willing to sell that toy for $50. But after hearing that comment, the owner of the toy store realizes that he has added leverage, due to dumbass Dubas’ comments, and so he asks for more. After all, because he is now at risk of disappointing this little kid, and because the toy store owner knows this, there is more at stake for Dubas than there was before he made these comments.
Dubas didn’t have to make that comment. It was completely unnecessary and he gave a ton of leverage to Nylander. That is a big part of why he looks particularly bad here.
