i think now u have to go through college

you must enter through the CFL or NCAA.

BTW this just bumped me up to level 3! :)

in the spring the teams do have walk in tryouts

ba a really good player

6 ft+ 230lb + 4.4 in 100 yard dash - no less. Bench press 500 lb. 20/20 vision. Can take a hit. Have a 6th and 7th sense of where the ball is at. Have been recognized at an early age as having talent. Be very very lucky... the probability of getting in is like winning the lottery

you better be really really good and can take hits and me able to run like the wind and throw well actually it depends on what position you want to play

Besides the obvious physical attributes, you need an agent. If the agent thinks you are good enough physically, he can get you a tryout. If the team is then interested, you have to go to ALL the off-season workouts and mini-camps.
If you have no college experience it's a tough road because the teams have nothing to look at as to how good you are. Be prepared to be a tackling dummy.
