The states are allowing basically anything so far, but the NCAA is hopelessly appealing to the supreme court/congress to restrict the states. Once the SCOTUS ruling is handed down, expect the NCAA to pass restrictions greater than the current, which is pretty toothless and generic.
What likely happens is a monetary cap on the engagement type. So, (these are arbitrary) max 1k for a Twitter post, 10k for autograph signing, 25k for a commercial, etc. The engagements themselves, or "proof of work" will be a big component to avoid 300k for showing up on campus.
The stars will reap the most benefit from the Texas brand. For example, those Capital One mascot commercials would almost certainly be full of athletes if created this upcoming season. Something like 12 mascots were apart of the commercial, including Texas, consisting of the most prominent national brands. This is the lucrative opportunity. Additionally, without a pro sports team in Austin, the visibility of the brand and ease of contracting players will create more demand for engagements than...say...Miami where they'll be competing with an NFL and MLB team (Marlins and Dolphins also using opendorse).
If we wanted to play by the letter of current law, the pitch to recruits is to piggyback your personal brand on the most lucrative brand in college sports. In addition to very lucrative opportunities to use your NIL thanks to the Texas brand, a steady flow of engagement opportunities will be available to you that would not be available in smaller or more crowded markets. While Georgia is pushing a lump sum payday, Texas can push a wealth building strategy. I think the market will ultimately do a lot of the heavy lifting in providing these opportunities, but there's a place for small business owners and fans as well. Then the bag is a tool, not an obstruction.
