Averaging segments and including the name

I have a awk line that averages rows.

So if my file looks like this:

Jack  1  1  1  1  1  1
Joe    1  1  1  1  1  1
Jerry  0  0  0  0  0  0
John  1  1  1  0  0  0

The awk line below skips column 1 and then averaged the rows

awk -F'\t' -v r=3 '{for(i=r+1;i<=NF;i+=r){for(j=0;j<r;j++){sum+=$(i-j)}printf "%s ", sum/r;sum=0}; printf "\n"}'

The end product looks like this
1  1  
1  1 
0  0
1  0

Basically what I want to do is print the first column as well... (the names)

So the end product will look like this:

Jack  1  1
Joe    1  1
Jerry  0  0
John  1  0

what modifications do I need to make?

I don't fully understand the logic, but.... I think you want this:
awk -F'\t' -v r=3 '
       printf("%s%c", $1, OFS)
       printf "%s ", sum/r;sum=0
   printf "\n"
 }' myFile

basically I want to bin starting at column 2 (and also print the first column). The bin size can vary , but in this case its 3.

I had some problems with that line, I dont quite understand the change.

awk -F'\t' -v r=3 '
  printf("%s%c", $1, OFS)
  for(i=2;i<=NF; i+=r) {
     for(j=0; j<r;j++)
     printf("%d%c", sum/r, (i+j-1==NF)?ORS:OFS)
}' myFile
