I want to question this. How do you measure or define Hard workers with the players coming in versus the players already on or recently released? And, how do you measure how much they love the game?
By your logic, Benny Cunningham, Lance Kendricks, and William Hayes should still be on the roster, because IMO, after all of the training camp practices I've seen in St Louis and in Irvine, these guys set great examples of hard work and leadership.
How do you know that Gerald Everett works harder and loves football more than Lance Kendricks or any other player from the Rams roster last season? Seems you are implying that some Ram players from the past season or so are not hardworkers and do not love the game. IF so, you would be better understood by saying who and why.
If I had to guess, I would say the common theme is that they are all Smart, with good football instincts, and team oriented, not me first.
