I agree with DonutDunker. I'd work with what you've got. Aubry is a decent trainee, I would keep him and make him your first training project. And Canales isn't a terrible prospect. Outside defense is a good skill and he's starting at respectable (the highest level), with "allstar" potential which is plenty for a new team, and most of the important guard skills are at least "mediocre". He might show some results if you can work him in to a tandem training with Aubry at PG/SG or SG/SF, and get his jump shot up. With a Level 4 trainer you'll see some improvement in both players even at age 20. If nothing else, you'll get the hang of training.
If new teams should be shopping for anything on the transfer list, it's cheap veterans.
