Irvin's suspension is the fifth for the Seahawks during Carroll's tenure as head coach, which started in 2010 - the most of any team in that span. According to ESPN, a few other teams have three or four, and ten have zero (Including the Eagles).
But the Seahawks lead the pack in this regard, without even counting cornerback Richard Sherman's overturned suspension last year. Carroll has previously had to defend players under his authority from drug charges during the 2009 draft.
The Seahawks also lead the league in non-scoring touchdowns since Carroll took over.
