i really believe this is an issue.
when you draft players or bring in free agents, 9 times out of 10, they will look to assimilate into the established culture in order to not step on anybody's toes.
well they are coming into a locker room with no vocal leaders, a locker room full of quitters from 2010, a locker room full of guys who like to help the opponent off the turf and give them love taps every 5 seconds, a locker room with very little accountability to each other, a locker room with players that blatantly avoid contact in games, a locker room where high priced vets are given playing time regardless of the quality of their player, a locker room where nobody ever tries to stir the pot when things are going bad, a locker room full of december chokers, a locker room full of faux leaders, a locker room full of one year wonders with multi year contracts, etc...
this is the culture new players are being infected by and therefore becoming part of the problem as well.
we have to cut it off at its head. destroying the core of this team, it's not working.
