Blackmon and Broyles were named to the preseason All-Big 12 team on Tuesday. Blackmon was named the preseason offensive player of the year.
This is the second time in about six months that a Sooner player has taken to Twitter to jab at Oklahoma State players.
In March, OU defensive back Tony Jefferson took a dig at OSU quarterback Brandon Weeden after Weeden posted a picture of the Cowboys co-South Division Big 12 championship rings.
“Love how @bweeden3 (Weeden) posted that pic of Big 12 ring,” Jefferson tweeted. “Didn't win that bud. #sorrypokes.”
The Cowboys and Sooners finished with the same record in the Big 12 South last season, but OU went on to the championship game because of their Bedlam victory.
