OL - to be objective we should look at what OTs and OGs were available (I don’t actually know) in free agency. Last time I saw an attempted stats focused review of all free agents it showed that everyone was about as bad as each other. Turns out no one lets above average OL hit free agency.
QB - He tried to secure Stafford and Watson, unsure if he was in the mix for other trades for QBs. He couldn’t convince them to join us which is a failing of the team, not him yet. The QBs available in the draft would not be helping us this year. So his failing was Bridgewater to Darnold… which turns out was a big mistake rather than a lower risk trade such as Minshew.
WR - impossible to accurately evaluate Robbie IMO, there’s too much crap going round.
Kicker - at the time was awful seeing people in and out in a conveyor belt but looks like we’ve got an upgrade albeit for this season.
CJ & Gilmore - Unnecessary to do both, should have pushed for Gilmore before trading for CJ. CJ definitely was a reaction to our standing plus Horn, but our CBS have managed OK with him.

So the main issues for me are moving on from Bridgewater to Darnold and the CJ trade, the rest is a wash
