The February release (and subsequent retirement) of Glover Quin, in theory, should have put safety Miles Killebrew in line for an elevated role in 2019. But, instead of moving from the bench to the starting lineup, ESPN.com’s Michael Rothstein believes that he could be on the roster bubble. 
“Killa” has shown bursts of promise while providing valuable special teams help, but he has yet to make a major mark on defense. Even without Quin, the Lions have other safety options from which to choose, including Quandre Diggs, Tavon Wilson, third-round rookie Will Harris, and rising sophomore Tracy Walker.
Killebrew’s practice performance in the coming weeks may dictate his NFL future. There are a number of potential outcomes, ranging from a starting gig at free safety alongside Diggs to a release that could expose him to the waiver wire just prior to the start of the season. There’s also the in-between that could sting the player even more than getting cut – Killebrew could be relegated to a special teams/reserve role yet again as he enters the final year of his paltry rookie contract.
If Killebrew can’t break through this summer, his best outcome might be a release and an opportunity to flex his hard-hitting style elsewhere.
I believe the writing was on the wall. Plenty of Special Team players has he excelled last year, the job was his. Hope he finds a job somewhere. Hardworking guy.
With a last name of Killebrew, perhaps the Minnesota Vikings would be interested… or the Minnesota Twins !!
Not sure about the Twins but the Milwaukee Brewers could certainly get some PR mileage out of someone named Killebrew.
