Look, he and Joe Milton are both top-edge competitors. They BOTH want to win the starting job, every single year they play, at every level.
Nico's coming in hoping he can win the job. He's bright, so he knows it is a huge uphill battle. He has to learn the offense, and not just in his head...in his nerve endings. It has to be automatic, thought-free. That takes...time.
He also knows that he needs to put on some weight, some muscle. Conditioning tatkes...time.
So he's smart. He knows his chances of winning the job this spring and summer is very slight. Maybe a bit better as the season goes on.
But he's also a team player, a good teammate. More than anything, at this point, he wants to be ready to carry the team if Joe Milton gets hurt. That's job #1 for Nico.
He's okay with the reality of his situation, because he's intelligent. Nonetheless, none of this is totally off the table. Because he's a competitor.
