Good one. I don't remember him doing much with the Raiders but that was a while ago. The weird thing about Wentz is that even though he was not great in 2018 or 2019 he didn't throw interceptions. Now he is leading the league in those. I wonder if the concussions have scrambled his brain and he is unable to read the defenses. That one in the playoffs last year was really bad.
I looked up Schroeder's stats. In 1990 the Raiders went 12–4 and it appears he had a perfectly serviceable, but by no means outstanding, season, but he didn't have to be outstanding because the Raiders had Marcus Allen and Bo Jackson to carry the load. Schroeder threw for 2,849 yards that season, which isn't bad but also isn't comparable to his 4,109 yards for the Redskins in 1986, his only full year as the Redskins' starter. (He did, however, throw both 22 touchdowns and 22 interceptions during that 1986 season, whereas in 1990 he threw 19 touchdowns and only 9 interceptions. It's fair to note that in 1990 he also attempted 207 fewer passes than he did in 1986, again presumably because Allen and Jackson meant the Raiders didn't need to throw as much.)
