Question about turkey breast thaw

I posted this as a reply to another thread and was hoping to get a few more responses. The situation:

I purchased two frozen 7-8 pound turkey breasts last Thursday with the intent to smoke Thanksgiving morning. At the time I was not aware of the USDA guidelines. I checked the breasts Sunday evening and they were not completely thawed. Would you feel comfortable smoking them Thanksgiving as planned or would I be better off starting over?
