I would counter the "annoying" durability problem by indicating that he's actually played tough through the injuries. If he's been out all season then annoying may be the right way to describe, but I think he's tough as hell
I also think he's by far the best player on our side of the ball offensively, love his attitude, and with a better qb can look like the AJ Green, Julio Jones, and dez Bryant's of the league. With more experience, if he turns out like those guys I think the price was worth it.
Mike Evans is a stud but wouldn't have been there at our original pick. Odell Beckham is better than I thought coming out of college, but I like sammy.
With regards to what we gave up, I honestly think nexus years qb class is a dud. Not a fan of Mariotta or Winston, and I think it's a little deeper where someone in the 2nd round could be had.
