Actually, East is correct because he said "at Pitt" which means when the Chargers played at Heinz Field. The Chargers won their last 2 away games against the Steelers.
Luck's next contract would have been negotiated at about the same time too. Either now or next year if he had kept his level of play from the last two seasons he played. Not sure he would have gotten the same number of years because he would have been 30 rather than Mahomes who is 24 now(25 during most of the season), but the per year contract IMO would have been similar. Maybe 7/320 or something of the sort...
I don't think Luck is motivated by money past some point. He seems like the type who would be equally happy and comfortable both with the 100M he earned during his career and with the 500M he could have earned in the next 10 years. I think he's more likely to be jealous of the success and ability to play football pain free, than about Mahomes' contract. I don't think he's ever coming back, either.
Now........I heard a question posed the other day on local radio. Asked if anybody on the Colts was worth the 10-year contract Mahomes just got. I immediately thought NO. I will say that IF anybody on this team would be the closest though, I think it would be Nelson. But no way in heck I'm giving ANYBODY on this team 10 years. In fact, I'm having trouble thinking of any other player in the NFL I'd give it to.
