I don't know the 'issues' with Guice. I don't know if there are issues with Guice. I never heard of him being difficult while at LSU, but I don't follow the program 24/7. My guess is Guice seems fairly relaxed and affable and this laid back gregarious manner probably rubbed some team officials the wrong way.
The NFL is inundated with arrogant assholes - from the commissioner through the owners on down. If Guice made a wise crack about some inane question these draft prospects are asked ( 'what's your favorite tree?') a team may have considered him a smart ass.
The gay issue -- who knows? I never heard anything. Supposedly the kid likes to stay home playing video games. Considering the environment he grew up in, that's a lot better than getting shot in the street.
Anyways, I hope he does well at the next level.

Wasn't he Mr Irrelevant while here?

TQ is an iconic dude. Most yards ever by a WR nationally, #1 in # of receptions in HS ever in LA, and now the last player drafted in 2018, i.e. Mr Irrelevant.

He is the next low key All-pro white dude at WR. He was done a disservice at LSU by shitty coaches...

Sure was. I felt the same about Russell Shepard. It's more an indictment of our decade of incompetence at QB which is a direct reflection of our inadequate coaching. Coaching scared that is. Les with his ptsd after 2008 never recovered. And our inability to develop a QB is clear below.

Where did he go?

Curious what other schools look like. Might not be much better?

Bama's may be worse which ruins my argument so let's not go there.

Every LSU player ever drafted bu the Saints.

Who took him? Also did Diarse get drafted?
