Hi Dan - Very easy for him to get going with the in-season Line-up Analyzer even though he didn't use the Draft Analyzer:
Just purchase license to "In-Season Analyzer", "ESPN" (or whatever his site is) and select the "Single League License (40% Off)". He doesn't need to purchase any projection sources as those are included with the purchase of the Analyzer (RotoWire, 4for4, ProFootballFocus and NumberFire). Total will be only $15.
Use the appropriate automated league import feature in the dashboard
Open the "In-season Analyzer" and click Sync Roster...this will import all of the players on all teams in his league.
That should get him going. Let me know if any questions come up. Thank you Dan.
