How about just plain confidence and experience? When our first team was trying to score a TD at the end of the game against Georgia's reserves, did any of you actually believe they were going to do it? Did the players themselves think it would happen? I'm not so sure after being rattled all day.
Two quick points:
1) Our skill position players are much smaller. I made a mental note years ago watching Alabama vs Clemson in national title games, "we won't be competing for titles until we get much bigger at the receiver position." Size at receiver and the ability to get physical separation from elite corners is a huge difference maker or at least a great equalizer. We simply didn't have the scheme or the player to make a play down the field.
2) I'm not sure what coaches tell players vs media, but the "every position is an open competition" line is getting old. Your program isn't going anywhere until there is a clear talent/experience pecking order on both sides of the ball. I bet Georgia, Alabama, and Ohio St all have very clear 1 and 2 deeps starting fall camp with few exceptions. It adds clarity and confidence for the program and helps the team understand what to expect from the players around them. I didn't know what to expect from Oregon on Saturday. Did the players know what to expect from themselves?
All this to say that Oregon has four head coaches (1 interim), a gazillion coordinators in the last 5 years, and a huge swath of players from the transfer portal. Georgia is a well-oiled machine at this point after years of building and consistency. It's disappointing that we played them at likely the worst possible time.
