5. Right stuff landing, basic AG roll with a -1 for every tacklezone on both the big guy and landing player.
Secondly you can put lots of people on the line to put more tackle zones on the troll. More tackle zones mean more chance of fumbling the gobbo. But a player will soon learn to keep the troll back one square with a screen of guards. (hope for a Blitz! kick off result!)
P.S.: I still hate to have no possibility to respond to a TTM oneturner.
