True but there is a chicken and egg situation. How much of them being bad fell on Flacco, fell on the receivers, fell on the OC. However, we know Flacco is 34, has never made a Pro Bowl, is 22nd in active Y/A, 22nd in active passer rating, 18th in active completion %, 24th in active pass TD % and 10th highest active interception %. Removing years he was hurt or benched, his average finish for fantasy is QB17.
In other words, he has always been a below average QB and he is old so it's likely only getting worse.
