Is it odd that Ceedee Lamb isn't getting touches in a contract year
It is odd whenever any top 10 wide receiver does not get enough targets per game during any season, contract or otherwise. Each season, there are a few receivers (or tight ends for that matter) who are 'always' open when they are covered. Lamb is one of those receivers.
An opponent's defense can play a factor every so often. They get paid too. Even receivers like Tyreek Hill have a 'bad' game from time to time but average or below average games should never become a trend for a top receiver.
