So there are 13 NFL quarterbacks who were drafted over the last three seasons and that have thrown 100 or more passes this season. Profootballreference.com shows how well any QB fares when blitzed (it’s in their splits decently far down the page). Drew Lock has fared very poorly against when blitzed this year. He has a passer rating of 41.5 and has thrown 1 TD and 6 interceptions. He is also only completing 47.5% of his throws when he is blitzed (defined as when the defense sends five or more players to rush the passer).
