Allen's supporting cast is trash, Lamar's is way better.
Ravens room has bigger names, I do think a lot of the Bills players are younger and are very underrated. They don't have an insane player in their receiving room, but they do have solid WRs across the board with different skill sets. Two solid tight ends and their running back room is good. Top 5 o-line in the league. Bills and Ravens defense are about the same in rankings as of now so that's a wash.
The Ravens have had to overcome the o-line being a massive weakness against teams like the Raiders, Steelers, and Chiefs. If anyone wants to watch a masterclass on how to avoid pressure and make big plays in the pocket, that Raiders game might have been Lamar's best game ever in his career escaping pressure and making plays out of it.
I agree the Ravens on paper have an edge at TE, WR, and RB. But the Bills definitely have the better o-line.
Ravens have also had to overcome the defense being the worst in the league over the first half of the season and Justin Tucker having the lowest field goal percentage in the league.
I believe I saw a stat (someone would have to look it up and correct me): Bills against playoff teams this year are 3-3 and the Ravens are 5-3. Bills have the better record, but they are probably in the worst division in football as of now.
