Well the 2019 team was 3-5 with Streveler starting and 4-0 with Collaros starting. So he had some impact. D wasn't getting it done by themselves, they got smacked around pretty bad in majority of games after Nichols went down.
Probably don't get to any of the post-19 Grey Cups if you don't host the West Final. Matt Nichols never hosted a West Final. Buck Pierce, Kevin Glenn and Khari Jones hosted 1 East Final each. Collaros has hosted 4.
Good to have some perspective. The only comparison that will matter in the end is Dru Brown from 2024 on vs Collaros from 2024 on.
