Sorry if this is a dumb question… but why the fuck is Marco Wilson on the field and Kei-Trel Clark isn’t (idk if I spelled that right lol)

For starters, I’m pro Kyler and want him to succeed. However, even if he is bad, I say build the line and keep Kyler. It doesn’t matter who you have playing quarterback if you don’t have a good line and to me, our O-line & Marco Wilson (because fuck that guy lol) seem to be the teams biggest issues
