I only use one gobbo on the roster since I play orcs mainly because of their high armour. when he gets beaten up (which he does get occasionally) I still have my blitzers to score. Oh, and I play with passing usually, not handing-off - that's what the thrower is there for, right

with skills I'd usually go for:
blitzers: guard, mighty blow, tackle; stand firm or dodge on doubles
thrower: accurate (helps him get some more SPPs), block... and then... I don't know, hope for a double to get strong arm or perfect spiral if you allow that skill
black orc: block

gobs: sure feet, sprint, catch, diving catch; block of course on a double... maybe jump up on a second one
linemen: block, tackle or dirty player, maybe kick on one; guard of course on a double
