I thought the penalty on Marsh was bad and now the league fines him as well. Marsh took a few steps and stared at the sideline not sure that warrants taunting let alone a fine. I think it is worse when players signal first down or when the whole defense runs to the end zone to celebrate a TO. Some QBs do their thing on TD passes, Watt does his sack celebration etc etc. I think they should let the guys have some fun, but be consistent.
