Sport shop function?

What does the sport shop do for you? I see the note regarding buying gear and equipment, but that's not much to go on. How does it benefit your players?

I'd like to know more before spending the money to open a slot for this building.

Thanks
Ten pieces of equipment that each add to a skill: Pass Accuracy, ERS, Stamina, Training %, Receiving, Tackle, Block, Penetration Strength, Speed, & Toughness. Three levels (stars) with increasing adds; 5, 10, 15. The % of the building level is what you save on the bid price.
The equipment lasts for one season, then you need to buy more.
Does the gear work the same way it did in GLB?
The equipment adds in just like the Strategy Building bonus does.
Thanks Dreadlords
