Just like Portillo, he has not signed an ELC and appears to be headed back to college for the last season prior to him becoming a UFA.
So, in the absence of an indication that he wants to sign, there is a reasonable amount of concern that he will walk.
I would not say it is 100% that Johnson walks as a UFA. But, I also think it is overly optimistic to expect him to sign with Buffalo, as well.
Fans are not privy to the conversations between Johnson, his family advisor, and the Sabres. So, we are left to guess as to what will happen.
And the Cal Petersen walking thing does make some people overreact. But, the Sabres have signed the vast majority of college draftees over the past decade or so:
