Conjecture. For sure both Collaros and Brown have benefitted from Winnipeg's development of a solid Oline and a scheme that offered pretty dang good QB protection. But how Brown might fare elsewhere is irrelevant to the opinion that we should have kept him here. The size difference between the 2 QBs is also irrelevant. After all, Doug Flutie was 5'!0 180lbs - bigger does not equate to more success or durability. For sure Zach is a warrior who, as you say, has had to sit out for extended periods due to serious injuries. The fact that he has suffered so many injuries - especially hits to the head - underscores my basic concern about him. After all, Collaros missed games in 2015 and 2016 with the torn ACL - not clear he ever recovered from that 100%. In 2018 he was sidelined for several games due to a head injury and he did not play for most of 2019 due to head injury. We have a valiant QB who is 35 and needs to avoid hits at all costs as they could be career ending. To me, it appears that is taking him longer to process things out there post-snap. Brown definitely got the ball away quicker than Zach and was more accurate and threw with velocity. That's how it appeared. Plus Brown knew Buck's offence. That's why I'd have kept him. But we didn't. Glad we've got Strevy though.
