"Trick" plays are no more difficult to execute than anything else. Many of the top teams in college and even the NFL rely on trick plays to change momentum and, often, to help win games that might otherwise be lost. Anybody who is on the field is capable of executing any football play imaginable. High school teams use trick plays, and the execution is usually excellent. Games like Wisconsin and Illinois and NW are when trick plays are needed most.
There's nothing any more dangerous about a trick play than any other play. Call it at the right time and execute it, just like a dive or a sweep or anything else.
We've seen teams from all over the country run trick plays already this year that have helped them win games. If there is a New KF, he would be well advised to try a few tomorrow: hook-and-lateral, flea flicker, halfback pass, throwback to the QB (which Hayden ran for a TD against Minny back in the day, BTW). An aggressive defense like NW's is an easy target for trickeration. Call it, Execute it. And it'll work.
