This is fascinating. What impacts would it have? My initial thinking is the following:

1. Everybody would get smaller. This change would place more emphasis on speed, so everyone on the field would get smaller to gain that speed.

2. The market for speed would get bigger among running backs and linebackers.

3. The market for shiftiness would get bigger among WRs and DBs. They're already playing out on the edge, so they'd have more space to operate. Increasing their speed wouldn't matter so much, but increasing their ability to work in space would be important.

4. Cannon-armed quarterbacks would be at a premium. You'd have to throw the ball 3 or 5 yards further just for a WR screen, and it would increase with deeper routes. Arm strength and velocity would become more important.

5. Running quarterbacks would go wild.

6. Would the hash marks get wider? That would place a premium on kicker accuracy over kicker range, and we'd probably see fewer long field goals.

7. Returns would be much shorter because kickers and punters could make returners run all over the field to get the ball. However, the returners would become much faster, so you might end up seeing more short returns and more touchdowns.

Wait. Did I just describe the CFL? Did I just waste that three minutes?
