Neither Thielen, nor Eric Wilson, a fellow over-achieving teammate who went undrafted but joined Minnesota in 2017, knew off-hand how many games they've played.
Wilson is up to 134 in his career and 73 as a Viking. He hit 100 while with Green Bay in 2023.
"Really? I didn't even know that," Wilson said. "Jeez. It's an honor. It kind of flew by in a way, but at the same time, I take pride in being present and enjoying the moment. It's an honor to have that many moments in this league.
"Harry's a baller, first and foremost, taking care of his body," Wilson said. "He loves the game, man."
Veteran defensive linemen Javon Hargrave and Jonathan Allen, who joined the Vikings this offseason, didn't spend much time processing their 100-game milestones.
Hargrave, who played his 139th last week, hit 100 with Philadelphia in 2022 and teamed with Brandon Graham, who reached No. 206 by the end of last season, retired after helping the Eagles win the Super Bowl and just returned for his 2025 debut on Monday.
"I really don't remember what I was thinking. I was happy because it's rare to make it that far," Hargrave said.
_Ever think about getting to 200?_
"Nawh, I can't lie. We'll see, but nawh, I haven't thought about 200," Hargrave's Southern drawl crept in. He said it's "very impressive" for Smith to reach the mark.
"A lot of things have got to go right. One, you've got to be blessed and lucky at the same time. It shows you took care of your body and how blessed you are because that's a lot of games in the NFL," Hargrave said. "I talk to him all the time for tips on how he's done it this long because 200 is crazy."
Jonathan Allen played in No. 118 last week and hit 100 with Washington in 2023.
"I don't know what my 100th game was, because whenever you accomplish something, all you can focus on is the next thing," he said. "I can almost guarantee unless somebody brought it up to him that Harrison isn't thinking about it. You just don't have time to focus on that if you want to be successful. You just take it day by day. I have no idea how long I've played. You just take it day by day and appreciate it when your time comes.
"I think the older you get, you just take it year by year," said the 30-year-old. "If I'm blessed enough by God to see 200, that would be incredible."
Already in his seventh season but still only 27, Byron Murphy, Jr., is scheduled to play his 100th game when Minnesota hosts Washington.
"That's actually crazy because, I think it was IP (Ivan Pace, Jr.), he was looking at how many plays I had in my career. I've been blessed and want that number to be a lot more," Murphy said. "Year 7, and I came in at 20 years old, so a lot of stuff has been moving fast, but just happy I'm here.
"I don't even want to know what number Harry will be at," Murphy added. "If I'm almost to 100, Harry's got to be like, I don't even know."
Greenway, who played all 156 career games for Minnesota, and former Vikings safety Andrew Sendejo (99 of 136 NFL games with Minnesota) joined the "Friday Football Feast" radio program on KFAN 100.3-FM to discuss their teammate.
