I'm gonna have to agree with Flash on this one. Especially in XBall, the need for clearly defined player roles is becoming smaller and smaller. Players must be fit, fast, and must posses the ability to play all positions on the field because in the modern high speed game **** can happen nd spots need to be filled.
I wouldn't quite say that ALL of Dynasty were pure front players in the traditional sense, their bigger guys like Rodney and SK don't quite have the pace to match Ollie and Angel. But aside from a couple of exceptions Dynasty's innate talent and youth allows them to be a very flexible squad at meeting the demands of the modern game. At a time when 10-man squads were very entrenched in experience and defined roles such as 'back players', Dynasty were at the fore-front of the evolution into 'multi-role' players. The drastic format changes over the last couple of years pushed Dynasty's unique talent to the top and left most of the other established teams who were previously comfortable, having to play catch-up.
As mentioned previously, in a 10-man squad there was the technique of making use of the fast 'front players' in fire drawing suicide moves. In 7 man on smaller more open fields like we have today, each player's role is more important and although players can still be sacrificed, their value is greater. In the 5man game, EVERY player is critical, as recent EXL matches have proved, you go a body down at the wrong time the opposition's superior numbers will run rings around you. Sometime less players on the field can result in stale games where teams are unlikely to make extreme moves because failure can result in loss of game control and momentum. Where XBall has this problem nailed is that if you loose one game it is NOT the end of the world. Risks can be taken because even if it goes pear shaped there is the chance of pulling the point back in the next game. The added bonus of less players on the (smaller) field means that games are a great deal easier to follow.
