Here's Berry's explanation in his own words, via an article on Sportsnet.
"I have tremendous respect for their football team and I have tremendous respect and a friendship with Charlie Taaffe," Berry said.
And "I know how bad it looks, but it's the right thing to do."
"It was strictly and solely for points value and I only did it because I really respect that football team and I know the potential that they have and the direction that they will be in."
"Let's say they beat us 28-14 this week, all of a sudden the 18 points we won by gets subtracted by 14 points and all we've got is a four-point advantage.
"I've been around the CFL too long to know that anything can happen."
It sounds to me like he's showing the Ti-Cats a lot of respect as opposed to giving us a big slap in the face.
