Trevathan notched seven stops in the Bears' 29-27 loss to the Steelers on Monday.
After missing the first four weeks of the season with a knee injury, the 31-year-old recorded just 12 tackles over his first four games before having his best outing of the year in this contest. Although it appears that the days of him being an elite IDP option may be over, if he can build on his effort in this game, he could re-emerge as a reliable fantasy option.
