The quarterback needs to be mobile and have the
ability to run with the ball on occasion. Most QB's
are sacked because they are too focused on just
one receiver. A QB needs the knack for throwing
long bomb for a touchdown. If all the QB does is
hand off the ball to a running back, then you are
going to lose more games than you win.
Exactly. Along the same lines, running backs also
need to be able to run well. They should be hard
to tackle. Our receivers should also be fast and be
able to catch the balls from the QB with a knack for
throwing touchdowns. If we combine these three
things with an offensive line that has a knack for
blocking well, then our offense should be able to
score a decent amount of points, which is what you
are looking for from an offense.
On the defensive side of things, we need players
that tackle well. When the opposing team tries to run
the ball, we need to tackle them before they gain
many yards. We also need defensive backs that are
good at covering wide receivers which will make it
difficult for opposing offenses to complete passes. If
the other team's offense cannot run the ball or pass
the ball well, then our defense is in good position to
prevent the opponent from scoring points.
