'The earliest the Bills could move on from Glenn is after this season. They’d have to do that before the third day of the new league year in March, when $6.5 million of his base salary becomes guaranteed. If the Bills were to cut Glenn at that point, they’d save a little more than $3 million in cap space in 2018, although Glenn could potentially cost more than $11 million in “dead money.” Potentially, that is, because the team could designated him as a "June 1" cut, which would spread out the amount of dead money over two years. That would put the Bills on the hook for $4.7 million in 2018 and $6.4 million in 2019. The cap savings in 2018 in that case would be $9.75 million.'
