I think it all depends on what Lowry nets. I don't understand how the cap works, but I see a balance that can be worked out to sign both. This is the first time in years we have an effective point guard combo as opposed to a controversy.
I think it would be smart to offer Vasquez something as soon as possible as opposed to letting him test the market regardless of his restricted status. I easily see a laker team offer a contract similar to Jose's in Dallas, 6-7 that I don't MU might match. I say try to pick him up at 5 early on. Then again it depends on what Lowry's agent throws on the table
