I don't get why everyone is always so low on Fajardo either. I suppose it's stylistic. Throws a pretty ugly looking ball, scrambles a lot but doesn't appear fast, doesn't have typical QB physique.
Results-wise he's had a perfectly fine career. Saskatchewan was a contender with him as their starter, Montreal won a Grey Cup with him, he dragged Edmonton back from 1-5 or whatever to 7-9 late in the year upon assuming the starting job, and here we are. The guy is never going to be the league's best QB, but nor is he someone fans should be perpetually dissatisfied with.
I'd categorize him as a high-end game manager. You're probably not going to over-achieve the ability of your roster with this type of QB. However, competent turnover-free play is often enough to outduel your opponent with the current state of QB play in the league.
How many QBs do you take over Fajardo right now? Rourke and Alexander for sure, and Harris is the defending champ so let's say those three (and I actually still wouldn't take Harris, but trying to be objective). After that...
Adams and Mitchell on their good days are better, but VA is inconsistent week to week, Bo is fragile and turnover prone. Their lows are lower than Fajardo's. Collaros is a turnover machine at this point, but still thinks he's the gunslinger of circa 2021, I wouldn't want him. Kelly hasn't played in 18 months, all while being dogged by controversy. We already saw what Maier has to offer.
Fajardo is in the mushy middle of QBs in this league, but circumstances sometimes see those guys sitting on the scrap heap (Alexander replaced him and has still never lost a regular season game, what can you do?), so I think he'll be perceived as a bandaid solution until proven otherwise.
