Also, keep in mind that Baltimore hasn't really won anything with Lamar Jackson either.
He's got a very good record (47-16, .746), but he's 1-3 in the playoffs and his numbers in the playoffs aren't good at all.
L, 23-17 - 14-29 (48.3%), 194 yds, 2 td, 1 int, 78.8 rating, 54 rush yds
L, 28-12 - 31-59 (52.5%), 365 yds, 1 td, 2 int, 63.2 rating, 143 rush yds
W, 20-13 - 17-24 (70.8%), 179 yds, 0 td, 1 int, 74.8 rating, 136 rush yds
L, 17-3 - 14-24 (58.8%), 162 yds, 0 td, 1 int, 61.5 rating, 34 rush yds
So they've averaged 13.0 points a game in his four playoff games, and the team is 1-3 in those games. It's not like their D has been totally lit up either, allowing an average of just 20.3 points a game. For whatever reason, he hasn't been able to get it done, and this guy is a former MVP.
