I meant what if the turkey was smoked when I bought it?
At that point I believe it would be too late to brine the turkey. BTW, I like smoking the turkey myself. One reason, besides great taste and texture, is minimal work involved. Just put it in the smoker on one side, then flip it over after an hour and wait about an hour and a half. Check the internal temperature and if it is correct you're done. No basting necessary.
