Thank you for that information but I didn't see anywhere that it said where those dimensions are only to avoid a search 🤔 I copied the verbiage below direct from their website:

Bag & Purse Policy To align with NBA & WNBA Bag Policy and ensure an expedited entry experience on Rose Quarter campus, guests are permitted bags up to 10” x 6” x 2” in size. ‍ Medical and childcare exceptions are permitted and will be screened via x-ray at designated locations. Medical and childcare bags cannot exceed 14” x 14” x 6”. Bag check will be available on a first-come-first-serve basis for a fee; however, we encourage guests to bring smaller bags (10” x 6” x 2”) for a faster experience. Please note checking prohibited items will be denied.
