With Lucas Johnson's decommitment, the remaining options at this point are down to a couple names to be aware of:
Antelope dual-threat QB
Montel Aaron. He has been a Temple commit for a few months but Temple just took a QB commitment a week ago from a local Philly kid. Here's Aaron's senior film:

If something there doesn't happen, former Tennessee prospect
Zach Weatherly is still an option. Lucas Johnson committed to SDSU before Weatherly could, so Zach committed to Chatanooga early during his senior year. From what I understand, Weatherly will officially visit SDSU this weekend. Here's his senior film:

If neither of these pan out, SDSU won't sign a high school QB and the name you'll be hearing plenty of this summer (I'm sure you already have) is
Seth Collins, the former Oregon State QB who was asked to play multiple positions toward the end of the season for the Beavers and announced his transfer decision this winter.
Collins (Granite Hills) was offered as an athlete by San Diego State during the summer prior to his senior year but it was clear he and his family were set on him playing QB in college. He proved to be an average passer at OSU but a serviceable one with potential. The Beavers used him in dual-QB system with another freshman QB early in the season, switching them out every other series and other methods like that because - if you've seen him play you already know this - his athleticism alone is enough to convince coaches to get him on the field somehow. Oreg St. probably thought they did enough to keep him happy with playing time at QB early on but when a mid-season injury occurred, they basically told him that his future with the program would be as an occasional QB/ATH. He decided to transfer shortly after.
Common knowledge says that he'll transfer to a lower level school, and SDSU being a local program will obviously have them in the discussion. The thing is, Collins has plenty of time to consider his transfer options because OSU is a quarter system school so he wouldn't be able to transfer to most schools until the summer. Since he'll be forced to redshirt this upcoming year, he will be looking for a school that has a senior QB this season with young QBs following behind that he could beat out and win the starting job. This basically makes him just like any other 2016 quarterback (ex. Lucas Johnson) since most are unlikely to play their first year anyway. Collins played as a freshman so by the time he's eligible he'll only be considered a redshirt sophomore, giving him three years at school to make an impact.
Will SDSU give him a try? It will no doubt be Rocky's call and if he believes they can develop him to be a good QB at this level. There's no reason to try and trick him into signing as a qb and changing the position because he'll only transfer again - he's done it in the past. There's also no doubt in my mind that Collins and his family have reached out to Rocky by this point.
