Less often - so risk of fouling out is higher. Re. alignment we try to stick to real world divisions but also prioritze keeping owners with 2 or more teams in separate divisions/conferences, so it can be a little off sometimes. And yes, if a player in the database is listed as having played for your franchise, then they are eligible to be added for that season. You just can't use a season from another franchise, that's known as "twisting."
