According to Pro Football Focus (PFF), they rated Burrow the best QB in the NFL this season. The biggest gaps between Burrow & Stafford concerned their response to pressure, as Stafford committed "turnover worthy plays" at almost double the rate of Burrow. For individual props, PFF likes the following:
Burrow over 24 1/2 completions, 12 1/2 rushing/receiving yards, over 11 1/2 rushing yards & under 1/2 interceptions, under 1 1/2 TDs, under 36 1/2 attempts, and under 4 1/2 carries. Similarly, with Stafford, PFF forecasts under 1/2 INT, under 1 1/2 TDs, and accepts the rest. According to the game logs at pro football reference, the typical stat line for each in their median performance this season would look very similar, with the big play edge to Stafford netting him a bit more. Their stat lines would look like the prop odds: 24 for 35 for 265 yards with net yards per attempt at 7.7 and a QB passer rating over 100. Defensively, Rams defensive line ranks much better than the Bengals, but the rest of the depth chart gets very comparable looks. Top-10 QBs against the Bengals during the regular season easily averaged a 100+ QB rating, until the playoffs, where even Mahomes ended up with a sub-90 passer rating. Rams defense equally stepped up in the playoffs, but also gave up a 95+ passer ratings 5 out of 7 games. Against top-10 passer rated defenses, Stafford averaged less than a 95+ passer rating, while Burrow did. The Bengals more pedestrian pass defense and Burrow's better-than-average performance against elite pass defenses and pressure suggest both QBs should have typically good games in the Big Game.
