Standard Norse Lineman:
Most of your Linemen are probably going to go this route in their development. Fend is a great choice as I already explained, though you may want to pick up a couple with Tackle first if you find yourself short in that department. Again Pro is an option if you find they live that long, or instead of Tackle if you already have quite a bit. Dauntless on a couple can also be helpful if you are in a league with lots of strong players. You may also want to consider getting one with Wrestle even though it duplicates some use with Block it is a skill worth having on your team.
For doubles I would consider Guard probably the best option as it makes it harder for the other team to hit you and easier for you to hit them. Norse teams also have quite a few players with Frenzy and Guard will help ensure that you are less likely to get in really sticky spots due to that. Alternatively take Dodge to help stay upright and play a more stand offish game. +ST is great and doesn’t require thinking about, the same with +AG. If you roll +AV ignore it for the doubles otherwise it can be useful to take it for the ones you put on the LOS. For the rest it is really 50 50 compared to extra movement.
Fouling Norse Lineman:
One way to make it harder for the other team to hit you is to foul them. Your players are fairly cheap compared to a lot of others so it can be a good trade even if you do get sent off! If you don’t then the extra numbers on the pitch lets you gang up on their players rather than the other way around. You will probably want a couple of these guys so you can hopefully ensure you have at least one available at the start of each half. Dirty Player is obviously the skill of choice here and follow it up by Fend to try and keep him as free as possible to be able to run to the target easily. More skills is somewhat of a waste and not really needed, but if he is fouling a lot and getting sent off chances are his development is going to be somewhat slow anyway. If you do then the usual Tackle or Pro are all you can really consider.
Doubles may point to Dodge being preferable over Guard, staying upright gives him maximum range to move and also helps if he needs to dodge obviously. You can consider Sneaky Git but if you are fouling right and getting plenty of assists in then you should be breaking armour anyway making it pointless. Stat increases follow suit as before.
Norse Linemen Summary:
It may appear that there isn’t really a great deal you can do with development of a Norse Lineman and to some extent that is true. They start with the most commonly taken first skill upgrade other Linemen would take which effectively puts them one skill ahead of the development curve. As such don’t worry a great deal if you don’t get them past their first or second skill as they will already be pretty useful to you. As your team develops your skill choices will lean more towards Fend and away from Tackle. Their team mates will be able to deal with Dodge players once the team is developed.
If you do find that you aren’t suffering much in the way of injuries and your Linemen do start getting multiple skills then you can perhaps consider sacking some of the ones who reach the third skill without a double increase. Getting more Guard is going to be very helpful to the team and the extra skills don’t really add a great deal. If you are short on players then I would still keep them until you get a reasonably sized squad. This also ties in with fouling as it is usually advisable to not get your players sent off if you don’t have replacements on the bench to bring on in the next drive. Remember you want to be the ones doing the hitting and avoiding being hit back, so also don’t be too scared of doing one dice blocks and make use of the fact they all come with the Block skill!
