LA Rams -4 / 10*
Was hoping that this would drop to 3.5 at some point, so I could buy it down to 3 just to be safe at the key number, but I'm seeing 4.5 in most places now, so I'm officially locking this in because I see the Rams winning this one pretty handily. The Rams have the advantage in almost every category, let alone playing with home field in the Super Bowl. They are a group of veterans, many of which have either been to the Super Bowl or have been itching to cement their legacy here for many years. Those that have been to the big game (including McVay with the coaching experience) have already experienced a loss there too and won't be keen to repeat their mistakes this time around. They also aren't going up against one of the best coaches ever in Belichick. Instead, they go up against Zac Taylor who was actually the QB coach for the Rams in the last SB, so him and McVay are both familiar with each other.
The biggest by far advantage comes in the trenches, with the Bengals being one of the most sacked teams in the NFL and the LA Rams having one of the most dominant DLs (now with Von Miller as a part of the squad too). That to me is the key to this game. Super Bowls are won and lost in the trenches, so having that be a HUGE advantage for the Rams, plus then adding in the veteran experience, home field advantage, and equally-impressive offenses, I see the Rams handling business today. Rams running defense is also stout, so if they can keep that up and move the ball vs a worse Bengals defense, Burrow will be stuck in long downs and playing catch-up mode, which just makes the case even worse when it comes to the Rams DL vs the Bengals OL.
Best of luck all & cheers!
