The game of football was not conceived to have a four monsters who weighed 250 lbs at 6 ft 4 running 4.5 forty times playing linebacker behind three 310 lb minimum lineman going against another five 320 pound OLs.

The players have gotten bigger. Expanding the field a mere 35 feet is pretty reasonable.

And as someone who follows the CFL pretty closely (And let me say, the field is a lot more than 35 feet wider...), I can say that concussions, while still an ever present threat due to the nature of the game, occur with far less regularity or severity than they do in the NFL or NHL.

Another way to reduce concussions would be to allow DBs to play more physical on opposing WRs at the line, but we know everyone loves offense too much for that to happen.
