The conservative approach. 3 Re-rolls is all you will ever need. You start with 3 Wrestle which makes the team pretty reliable at Blocking. you also start with 1 Sure Hands player which means you don't have to worry about using a Re-roll on pick ups. Just make sure your runner is protected if you defend first half. Stand Firm and Grab give you some solid pitch control too. While your team isn't especially fast you do have 3 Jump Up players which is useful for staying mobile and can give you free blocks from a prone position.

Similar to variation 1 above, but you drop 1 Lineman and a Re-roll for your 4th Vanguard Blitzer. This gives you your full compliment of Blitzers which means you start with 4 Wrestle. Which makes Blocking pretty reliable. It also increases the likelihood of MVP landlng on one of your positionals, which is good for development. I'd recommend starting with 3 Dedicated Fans, which means you are left with 10k. You can increase Dedicated Fans to 4 if you like, or keep it there which means you can get an Apothecary after game 1 or save up for your 2nd Runner.
