IRVINE, Calif. -- Aaron Donald's holdout is expected to reach its seventh day Friday, with no real end in sight. The game's greatest interior lineman is engaged in a high-stakes game with the Los Angeles Rams, who appear to find themselves somewhere in the space between doing what is sensible and doing what is right

"Greatest" and best are two different things. Greatest denotes someone who has had a career. Donald has been around 3 years. Merlin Olsen is by far one of the Greatest interior linemen / DTs to play the game. But he had a 14 year career. Olsen proved himself over a career. Donald is just getting started.
To use the term "Greatest" when describing Donald is incorrect and premature.
