Richie Incognito's Unfriendly Twitter History with Jonathan Martin

Richie Incognito Day at Extra Mustard rolls on. After finding one past unfortunate Tweet sent by the suspended Dolphins lineman, we decide to dig a little deeper and found Incognito has a strange history with teammate Jonathan Martin on Twitter.

The NFL's growing dossier of evidence of Incognito's harassment of Martin now includes threatening, racially-charged text messages and voicemails purportedly sent from Incognito to Martin.

Over the course of the past year-plus, however, Incognito also checked Martin on Twitter several times, usually calling Martin a "weirdo." In a few cases Martin responded. What does this all mean? Well, we don't know yet, but it's part of the disconcerting puzzle.
