Actually, many MVC players have fared pretty well after transferring to higher-level programs.
Here are a bunch of recent MVC players who left to transfer to bigger programs and their stats show their numbers were pretty good-
Dru Smith left after 2 seasons at Evansville, and was an immediate starter and double-digit scorer in the SEC at Missouri. He lead the team this year in minutes played, points/game (14.3), assists/game (3.8 ), steals/game (2.1), and he shot 42% from three in SEC games to lead among qualifying players.-

Liam Robbins left Drake and played this season in the Big Ten at Minnesota as their starting center His numbers for a Big 10 team were very good and did not decline very much, considering he played fewer minutes per game at Minnesota.

Ryan Taylor was another former Evansville player who left and transferred to a Big Ten team. He played the 2017-18 season at Northwestern, where he started every game, though he played a smaller role than he did at Evansville. He finished 3rd in scoring for a bad Northwestern team, averaging 9.8 ppg,

Deontae Hawkins is another former Illinois State player who left and played his final season for a Power 5 team. He played for Boston College of the ACC in 2017-18. He was an immediate starter, but his year there was shortened by a serious knee injury. But in the games he played, he put up numbers that were comparable, and in some cases better (he was leading the ACC in rebounding when he got hurt) than he had at ISU-

Reggie Lynch is another former Illinois State player who left and transferred to a Power 5 team. He played his final 2 seasons at Minnesota of the Big Ten, where he was an immediate starter and productive player (until he was dismissed from the team and kicked out of school). And his stats got better in the Big Ten compared with his stats in the MVC with ISU!-

And the most recent was
Javon Freeman-Liberty who transferred from Valparaiso to DePaul of the Big East. His scoring numbers did drop at DePaul, but some of that may have been due to DePaul's point guard (Charlie Moore) hogging all the shots. His other numbers remained comparable to what he produced in the MVC.
