Thrift had a really bad Tour event at Seminole earlier this year, only caught 1 fish on day 2, ended his streak of limits and caused him to have a triple digit finish overall.
If I remember correctly, Bassfan does not consider Costas in their rankings, for some reason.
Thrift is quite simply the best "junk" fisherman on the planet. 9 out of 10 times, he can make something out of nothing.
