Replacement

Thomas demonstrated strong edge-setting ability against the run, but ineffective pass-rush depth and a costly pre-snap penalty kept his overall game at replacement level.

The full breakdown

Thomas' 61.9 overall mark was defined by a solid run defense (70 grade) counterbalanced by quiet, undisciplined pass-rush reps (58 grade). He stood out against the run by squeezing down the backside to make a critical third-down stop at Q2 04:46 (+1.5) and setting a firm edge against Patrick Paul for no gain at Q4 07:17 (+1.5). However, 33 of his 42 snaps came rushing the passer, where taking overly wide rush angles gave up lane integrity on consecutive third downs in the first quarter (Q1 07:09 and Q1 04:13). A careless defensive offside penalty at Q2 01:50 (-1.5) further suppressed his grade back down toward neutral.
