Some of these aren't flag plants, they are hot takes
Is there a difference?
Flag plant is like taking ownership. The US planted the flag at Iwo Jima symbolzing the island was ours and we were winning the war. So I might like lots of guys for fantasy this year but my flag plants would the guys I believe in most and am most willing to put my reputation on the line for. A hot take or bold take is something you don't really think will happen but you have a hunch that something way out of left field could happen.
For example, flag plant could be saying Jameson Williams in the 5th round is my favorite pick. He's my guy there, I am taking him every time, he's on almost every team I draft. . A hot take would be saying Jamo will outscore Amon Ra and be a top 5 WR in fantasy this year.
First of all; big fan, I think you know that. Second... you lost me with Iwo Jima. I get it but, too big.
I think it is a distinction with... at best a minor difference.
FTR I took Jameson at 5.04 as my WR2 in FBG Home League Uno (23rd WR off the board) and he's my favorite pick. Passed on Sutton, who I love this year, McLaurin and Moore at 4.09 because I was hoping to land Jameson at 5.04. Couldn't be happier. Got him as my WR3 (28th WR off the board) in my actual home league. But, I don't view that as a flag plant, I view that is as an outcome that wouldn't be terribly surprising to most. But, maybe I'm wrong about that.
Is that a flag plant?
ETA: I despise using the language of War when discussing sports. In the biggest way possible. They're silly, low stakes games for anyone but the people directly involved*. So that's probably jading my comments.
*I have opinions about the counter arguments to this but, I will refrain and hope no one talks about it.
