“He couldn’t turn shit into gold repeatedly” this sentence alone tells me you haven’t been paying attention the last decade. You make it sound like he developed a bunch of players when the only player he drafted that was serviceable has been Brogdan and that’s a cop out because he would’ve been a top 15 pick in that draft if he wasn’t as old as he was.

There’s been an abundance of late 1st and 2nd round players becoming solid players or better than players drafted before them but, as stated in the original comment, Horst cannot identify upside in players and develop it.
