I hope it's not too late for giving you advice for your line-up...
Oh well...
Make sure you survive. That means:
First of all, the recommendation that you get a high ff IS useful, unlike what you think - and said in your first post. The reason is simple: more ff means more money, i.e. that will allow you to pay for the players who will replace the numerous casualties you will certainly get from playing against such big teams in your league...
Secondly: buy an apothecary! for most starting teams, this is not essential if they want to have a perfect line-up to win matches. However, in your case, I think that it is anyway unlikely that you will win your first matches, facing teams much more experienced than yours. Therefore, you'd better buy that apothecary.
Then, consider your money saving options:
You can expect to get quite a few casualties against your team in the beginning. I would not buy too many positional players if I were you. Those guys are more expensive, and their additional skills will not make up for the fact that your team is not that resistant as a whole, compared with your future opponents. That might seem pessimistic, but I would even consider not getting a single catcher (only 2st and 7av). Blitzers could be a proper investment since they are supposed to be slightly harder to knock down, but still... In the end, the more linemen you get, the better in my opinion.
- On top of that, linemen are harder to develop than blitzers, catchers (both of whom will usually be the ones that you will make score) and throwers (lots of completions...). If your linemen collect the first MVPs, they should therefore be skilled faster and give your team a solid base of players, and make it more stable than the guys who have over-skilled positional players but useless linemen... -
The other money saving issue is in the amount of rerolls you will buy. Remember they cost twice as much as in the beginning once you start playing. Do you really think you will have cash to spare in your first 10-15 games to buy rerolls at double the price, while you find yourself forced to replace all the players that will be injured?... Unlikely.
I think you may as well buy rerolls to play comfortably for the first 15-20 matches. That means at the very least 4 reroll in my opinion.
I would see as a possible line-up (but of course, there are other possibilities, following the advice I've just given):
2 blitzers - 180k
9 linemen - 450k
1 apothecary - 50k
4 rerolls - 240k
8 ff - 80k
= 1Mgc.
I know such a team will certainly suck in the short-term, but at least you will be able to survive your first matches and have a good development potential.
If you know that ALL your opponents are way more developed than you, you might even consider ditching the two blitzers for one more reroll and either more ff or a thrower (just to have one guy to develop so that he will be ready to make good passes once the other positional players can be hired in your team) + 10k spare...
Good luck.
