To me, this situation boils down to 2 things:
1. Richie Incognito is a complete jackass.
2. Jonathan Martin is soft.
#1 we all knew anyways, so let me elaborate just a bit on #2. What Incognito did to Martin as far as the racial slurs and such crossed the line, no doubt. He is a jerk and a bully. But, on to Martin. This is the NATIONAL FOOTBALL LEAGUE. You are a grown man. This is your livelihood. To me, you cannot let some bullying and getting picked on cause you to leave your career behind, even for an abbreviated period of time. He needed to either stand up to Incognito himself or go to coaches/management without sacrificing his career. There are A LOT of people around the world who are going through MUCH worse things, yet still getting up to go to their sh*tty 9-5 job day in and day out.
Just my two cents.
