Brace your self to grasp that this puzzle is even cleverer than you first suppose… This is a particular one…

The seven-letter reply is:

GORILLA!

Why? Firstly:

Count up the variety of instances every numbered participant receives the ball to get the next 29-number sequence:

66, 117, 116, 32, 100, 105, 100, 32, 121, 111, 117, 32, 115, 101, 101, 32, 116, 104, 101, 32, 95, 95, 95, 95, 95, 95, 95, 32, 63.

^{Note that if you happen to depend on the CSV file somewhat than counting the passes within the GIF (which might take a really very long time!) it’s worthwhile to low cost the preliminary incidence of ‘1’, as that is the participant simply being in possession of the ball, not the results of a accomplished go – thus there are 67 1’s within the file, however solely 66 of those are accomplished passes.}

Next, discover:

That the quantity 32 crops up a disproportionate quantity of instances right here. Since the quantity 32 is the ASCII encoding for an area, this means we must always convert every quantity into its ASCII equal. This yields (ordering the gamers numerically from 1 to 29 by their shirt numbers):

But did you see the _______ ?

To change the underscores with a seven-letter phrase, word that:

This puzzle is an adaptation of a really well-known ‘selective consideration‘ take a look at by Daniel Simons and Christopher Chabris, which @F1Krazy inadvertently linked to within the feedback! In this, a bunch of white-vested gamers and a bunch of black-vested gamers go a basketball between one another and the viewer is requested to depend the variety of passes by white-vested gamers. The catch is that on the finish of the train the assessors reveal that whereas the viewer was so targeted on counting the passes, any person wearing a gorilla go well with walked proper via the center of the gamers, turned to face the digital camera and beat their chest earlier than strolling off once more – and a lot of individuals don’t discover this whereas their consideration is targeted on the counting!

For this motive, I consider the ultimate sentence the OP is in search of is:

But did you see the GORILLA ?

HOWEVER – HOLD THE PHONE… So far that is little greater than a glorified educated guess. But there may be extra – and it’s value wanting into. You see, there may be extra that we are able to do with these knowledge than merely counting the variety of passes. We can even:

Count the variety of passes between every pair of gamers and tabulate the outcomes. This will be achieved in one thing easy like Excel (see the post-script if within the methodology).

If we do that in Excel after which shade all cells (utilizing conditional formatting) which might be non-zero, we see the next:

IT’S ONLY AN ACTUAL GORILLA!! Which we did not initially see whereas we simply counted the passes!!

Mind. Blown.

^{Post-script 1: Excel methodology:}

^{– Import the CSV file, so every quantity occupies its personal cell in row 1, beginning with cell A1.
– In row 2, use the method =CONCATENATE(B1,”-“,A1) to type pairs of passed-to-dash-passed-from.
– Write the numbers 1-29 in cells C4 to AE4 and once more in cells B5 to B33 – these type your labels.
– In every cell inside the grid shaped by these two label axes, enter the method =COUNTIF($A$2:$CRO$2,CONCATENATE($B5,”-“,C$4)). This then counts the variety of instances every pairing happens among the many concatenated numbers in row 2.}

There could also be an easier method to obtain this, however this was my approach!

^{Post-script 2: I additionally word the OP’s selection of title for the character on this puzzle:}

^{In the US sitcom Friends, Ross has a pet capuchin monkey known as ‘Marcel‘! Clearly a pop-fiction nod from the OP there to an ape/monkey connection 🙂}

(In response to this remark the OP identified that their true inspiration behind the title was Marcel Delgado, the stop-motion model-maker behind essentially the most iconic of all display screen apes, the unique surprising gorilla, King Kong. I would not be stunned if the identical man proved to be the inspiration behind naming Marcel the capuchin monkey from Friends as properly…)
