I'd like to see Pass Rec Courage and Punish Receiver removed and a new attribute implemented: toughness. Toughness could be used across all positions. It could impact how much pressure affects a QB's throw, how much of a stamina loss a player takes from getting hit (RBs for instance would gen on average with higher toughness than WRs), and how much an injury hinders the player's performance (some players are better able to 'play through' an injury than others). And of course it would replace both the Pass Rec Courage and Punish Receiver traits.
