This doesn't work for you?
I can recheck the steps but I'm fairly certain this is exactly how I did it.
1 Download just the roster file from here:
https://www.dropbox.com/sh/1s3ckdpgd...xB2WIlAaa?dl=0
2 Plug USB that is ok to format into Xbox.
3 Go to Settings - Storage and format the USB stick
4 Go into your hardrive, find NHL 14, find a roster save and copy it to your usb
5 Plug USB into Computer
6 Download MODIO.

7 Open MODIO, click Open a Save and open the roster file off the usb
8 In MODIO again click open a save and open the roster file you downloaded in step 1.
9 Copy the Profile ID and Device ID from the XBOX roster file and paste them into the downloaded roster file.
10 Click Rehash and Resign
11 Delete the roster file from your usb stick
12 Copy the downloaded roster file onto your usb stick
13 Plug the USB stick into your xbox
14 Go to settings-storage and copy the roster file from your usb stick to your hard drive
15 The new roster should now show up in NHL 14.
