McVay has already PROVED he knows how to win a Lombardi. This team is on the cusp of becoming a Super Bowl contender for years to come starting this year. McVay has improved his offense, making it more adaptable for not just Stafford's skillset but for his successor as well. More QBs can play this current system. A pocket QB who can make presnap reads and go through his progressions quickly making good decisions. Physically, he needs to throw with velocity, accuracy, and touch in the short to intermediate ranges. Believe it or not, that is exactly what Purdy does.
Defensively, we need to see what Shula does with the defense, but I see a DC who probably will be flexible in how he plays his guys. I also expect his secondary will be aggressive in both man and zone coverages.
I do expect the Rams to take a QB in the first round. Whether or not they trade up to get one will be determined by the board and whether or not Les can find a trade-up opportunity. The reason being they would want that 5th year option for a first round pick. This would allow them to redshirt him the first year behind Stafford and still have control over his rights for another 4 years. This opens the door to a few more QB possibilities. Guys like McCarthy might drop to 19 and he has the basic skillset to play in Sean's revised system.
If they trade up I expect them to grab Nix he has the perfect skillset IMO for what McVay wants. Snead has to expect that the Seahawks will do what they must to grab Penix. They are moving the 2023 Washington Husky offense to the NFL in Seattle. They know it would be a huge fan draw to have Grubb and Penix as well as their new OL coach all as Seahawks.
