Metta still a good pick-up?

Metta is back on the waiver wire for my 10 man h2h Cat's league. Still a good pick-up?

I was also looking at Randy Foye and Vince Carter.

This is my team: http://i.imgur.com/6I18v.png

I'm thinking about dropping Valanciunas for Larry Sanders and Kawhi Leonard for Metta.

Any advice? Thanks
