Not if you're purposely trying to keep the arm in line with the body.
Welcome to the ttw fray ...
I agree, Fed is indeed Goat ... is that the same as boat.
First ... a point of clarification ... I now state that as "the hand travels with the shoulder line in ATP FHs". I make that distinction now because in the course of video review, some bent arm FHs will have the elbow ahead of the shoulder line in the forward swing. The constant across straight arm FHs and bent arm FHs was the hand travels with the shoulder line. The reason for these previous discussions was the false assumption many of us had here when we heard the term "lag". We thought "arm lag", not "racquet lag" ... and certainly not ESR/ISR arm rolling lag. The SSC is not my thing ... brother
@Dragy loves him some SSC .... at age 61 SSC becomes STSC (stretch tear shortening cycle).
My old thread on shoulder/arm/hand moving in sync (

I actually don't agree with the implication it takes effort and tension to keep the arm in line with the body ... in fact I think it is it's natural state/position:
I'm aware of advanced techniques of ESR shoulder/arm locking for forward swing ... but put that to the side for a second. Let's talk about an average adult rec FH with no ESR locking:
The upper arm is attached to the shoulder joint ... it comes along with the shoulder/torso rotation forward for free ... no choice. I don't hit a ESR locking FH ... and I don't consciously make the upper arm come with the shoulder line, and I don't consciously make my hand travel with shoulder line rotation. I actually think it would take conscious effort to make it do something else. If I turn my shoulders back in the unit turn, than my upper arm and hand come with the uncoiling.
I also think the "tension" thing is a bit of a fictional narrative. If our arm was tension-less during a FH swing, our arm and hand and racquet would be hanging down beside our body. We maintain arm/hand structure/location with effort. Very relaxed effort ... don't notice it because it's muscle memory, but it's not all gravity free. Fed doesn't get down to pat the dog without some arm/hand muscle effort. My take is just keep the arm relaxed ... no death grip ... and proper timing of 1) shoulder/torso rotation ... followed by 2) arm added effort going into contact .... leads to smooth easy power.
Hip/torso/shoulder/arm rotation:
On a semi open FH unit turn with hips turned max past feet, and shoulders turned max past hips ... the torso/shoulders will come immediately with hip turn. It has to ... that is what max means ... no hip -> shoulder lag left to let hips go first and leave shoulders in place. That doesn't mean you couldn't turn shoulders less than max past the hips ... which would allow initial hip turn with shoulders left in place soon to follow. Or .. no shoulder turn at all ... and introduce shoulder turn in forward swing (One of our great past posters SinjinCooper said that is how advanced players often hit their neutral weight tranfer FHs ... introduce shoulder turn in the step forward).
There you go
@Curious ... you sneaky guy .... sucked me in.

You know
@Dragy is about to go all SSC on us now.
