Two different arguments happening here really...
Argument #1: We have a terrible recent history with 2nd round draft picks, and some posters would like to see those guys playing at a higher level, or playing at all.
Argument #2: It doesn't matter what round they were drafted in, the best player's should play.
Both actually valid arguments.
We do have a terrible history with 2nd round picks over the last decade or so. There's just no way to argue that guys. Not everyone has been a bust, but our most successful 2nd round pick is a safety with bad knees who can't seem to stay on the field.
I agree that I would love to see some 2nd round picks produce more than ours have.
By the same token, I also don't care what round a guy was drafted in. The best players play. I sure would bench a guy like Arian Foster (undrafted) just because Ben Tate was picked in the 2nd round.
Sometimes those last round picks surprise the hell out of you, defy expectations, and become major players. Sometimes those early picks that should develop into quality starters don't, they bust.
But certainly the last decade has been bleak for the Lions after the first round, with an exception here or there, like a Sammie Lee Hill. But our draft team clearly needs to do a better job identifying good talent instead of those "could have gone in the first round if not for...." guys.
