It means they're going to keep at least 5 because that's how many are on a basketball roster.
You’re not going to go out and play with five point guards,” LaFleur said, via the team’s website. “You need a speed guy. You need a guy that’s got short-area quickness … we’d like to have a couple guys that are versatile enough to do both of those things.”
And they need verstile guys or different aspects they're looking for....
I can't look them up right now, but I'd compare them to the Falcons Super Bowl roster.
Adams is like Julio
Allison is like Sanu (was it?)
MVS is the speeder's Gabriel? (I think)
Graham is the receving TE
Lewis the blocking TE.
