i'm stuck on which tempo I need to be running for my team http://whatifsports.com/hd/TeamProfile/Ratings.aspx?tid=5134

My theory was since my team overall is not very good and likely to not be favored much this season, I should run slowdown tempo to atleast limit possessions... the issue is i'm only scoring maybe 45 points a game..

Tempo-wise, I don't think it matters much because you probably won't be in a lot of games this year due to your very young team.  In games where you think you will be competitive, I would definitely do slowdown to try and limit possessions. Looks like you've got solid freshmen though, I would consider starting 5 freshmen in order to give them a improvement bump.

very good idea, i'm also taking this as an opportunity to practice a press defense so I can run the half court press/man

You're only scoring 45 PPG, but you should be giving up a lot fewer points on D than if you were running a normal tempo.

i'm switching to normal tempo tonight and the spread (not like its really accurate) says its a push.... I felt like I recruited solid talent with sky high potential... it's going to be hard to wait for that potential to get filled though

Yes this is a game of patience.  Many of us plan so that our teams mature in 2-4 months from now.

Use that time to try different things like tempo, or let freshment start to gain WE and their ratings will go up faster.  Things like that.
