Look, I'm not having a debate one way or the other I'm just going to answer your question directly..
it's the same reason a guy like Tom Brady and Brock Purdy fall did they have blown knees? I know a lot of players that have fallen of all different positions that were not injured just happened to get overlooked and fall in the draft because the drafts not perfect there's some undrafted players lots of them that make the Hall of Fame the draft is not a perfect place I'm not saying this kids gonna be good or not but you're off base by predicting doom and gloom of what you think is historically if you're a low draft pick you probably have no chance in the NFL and I'd say you have less of a alert when you're picked and lower because a lot of reaches happen in the first round.. Expert teams that are supposed to be filling BPA versus need but go with need... That's why the lower the rounds you get you get a guy like I don't know Duran bland how does he get into the fifth round it happens you know it wasn't an injury..
And I'm just going by what some New England fans reactions they're upset they didn't get enough for him they seem to like him I don't really know much about him I didn't even watch the game he beat Buffalo you know when they had backups but he played very well in that game regardless if you wanna look at it as a preseason game it wasn't a preseason game but it's OK to feel good about the guy until he proves one way or the other who's right...
