Do I still have a pick for this week? I last picked Sunday with Brown added Monday.

Yes Barry, you have an Add/Drop to use this week. I checked the transactions and see that you added D. Brown on the 9th, which was for week #14.
Week #15 transaction period runs from Monday, the 12th to Sunday, the 18th. Each team is allowed 1 Add/Drop and no limit on Add/DL or Add/ML moves. Do remember that there is a limit of 3 DLs and 2 MLs on each roster.
