I'm creating this thread to hopefully get some great advices from you experienced Blood Bowl coaches

I'm playing a rookie Orc team in a semi-perpetual league (one season at a time).
This season, I'm in a division with 5 other teams between 1000 and 1500TV.
My team is as follows :
4 Black Orcs
4 Blitzers
2 Linemen
1 Thrower
3 Rerolls
990k
Extremely standard.
I'm planning to buy next an apothecary, a troll and that's it (no 2nd thrower, no goblins).
Here's my development plan for this team :
BoB x4 - Block, Guard, SF, MB, [no double], [+St]
Blitzer x2 - (Block), MB, PO, Frenzy, SF, Tackle, [Jump Up, Dodge], [+St, +Ag, +Mv]
Blitzer - (Block), MB, SF, Guard, [Dodge], [+St, +Ag, +Mv]
Blitzer - (Block), Kick, MB, SF, Guard, [Dodge], [+St, +Ag, +Mv]
Thrower - (Sure Hands, Pass), Kick-Off Return, Block, Accurate, Leader, [Dodge, Strong Arm], [+St, +Ag, +Mv]
Troll - (Loner, MB, Really Stupid, Regen), Guard, SF, [Block, Pro], [no stats]
Lineman x2 - Block, Tackle, Fend, [Dodge], [+St, +Ag, +Mv]
The reasoning behind this :
- Bobs are rocks, providing immovable guards. I think 5 guards is enough with the Bobs and troll, so it's not a priority skill for the blitzers.
- Blitzers are here to hurt the opposition and get a numerical advantage.
- I'm giving kick to a blitzer as I don't see it on another player (linemen will be on the los) and it doesn't seem to hamper the team too much to take a blitzer skill. I'm giving it to the 4th blitzer who gets to lvl 2 (MB first for the 3 other ones).
- The thrower is primarily a ball carrier inside a cage, but I'd like to have a credible pass option eventually. KOR first before block to counter low mv, and he shouldn't be hit too often.
- The troll is a road block.
- The linemen provide tackle (complemented somewhat by frenzy on blitzers) and fill the los with the troll
My preferred defense formation as a rookie team is currently as follows :
----|--LmTrLm--|----
--Bl-|-Bo---Bo-|-Bl--
-Bo--|Bl-----Bl|--Bo-
The reasoning is to force my opponent to blitz a BoB if he wants to create a gap (or to get rid of the los).
Well, that's it for now.
I'll post later with the roster of my first opponent (~1350TV undead) and my plan for inducements.
