Is Richie Incognito's Dad Posting On Dolphins Message Board? FinHeaven User 'Idrd1994' Accuses Jonathan Martin Of Drug Use, Suicide Attempts
"By examining idrd1994’s post history, fellow FinHeaven user “TheWalrus” makes a compelling case that Incognito’s staunchest Internet defender is actually his father. According to TheWalrus, idrd1994 "only talks about the offensive line, praises Jeff Darlington (who Richie 'trusted' to write the big feature on Richie) and constantly refers to Jason Smith, the legendary #2 overall draft pick bust of the Rams, who was taken when Incognito was there."
TheWalrus continues, pointing out that idrd1994 had previously posted about growing up in New Jersey and watching the New York Jets while they still played their home games at Shea Stadium. Deadspin notes that Richie Incognito Jr. was born in New Jersey.
In addition, TheWalrus discovered that the user name idrd1994 had also been used on a message board for RC car enthusiasts. Sure enough, the idrd1994 account on the RC car forum identified the poster’s hometown as Glendale, Ariz. The family moved to Glendale when Incognito, Jr., was 11 years old.
The idrd1994 user name pops up elsewhere. Deadspin discovered an identical account on MyLife.com, which identifies that poster as Richie Incognito, a 63-year-old man from Glendale, Ariz."
