Koren Robinson- He was one of the most talented WR's we have ever had, he had good size, great speed, could make some amazing catches, could take any ball to the house, yet he could never put it together. He had a few incredible kick returns and a few quick slants to the house. He was my favorite player on the Seahawks. He totally and completely let me down I don't think he strung together two 100yd+games once in his career. Very very frustrating and I think Holmgren gave him too many passes, should have laid the hammer on him right from the start and his career might have been much different.
Jeremey Stevens- Was amazing in college and has forever tampered my excitement for draft picks. I was in the hospital the day he was drafted and literally yelled with excitement when we got him. He had the size, speed, and talent to be one of the best TE's ever. He was just way too immature and had too many drops or penalties in crucial situations. He was a guy who would be unstoppable one game and you'd shake your head the next wondering what the heck is wrong with this guy.
Shaun Alexander- I know he is one of the best RB's in the NFL while he was playing but he is a perfect cause of a guy who never reached his potential and cause much frustration for Hawk fans. During our Superbowl season "Alexanders Contract Year" he was a tough runner and played to his potential. Could you imagine if the 3 years prior or even for 1 or 2 years after if he had played with the same toughness and will to fight for an extra yard as he did that year, he would likely be going into the Hall of Fame. He drove me bat $hit crazy ever time he'd fall down for a loss by a arm tackle from a CB or Safety, or when he'd qb slide instead of lowering his shoulder to get the 1st down, or even when he'd slide out of bounds instead trying for the first. Alexander had all the talent in the world and one of the best offensive lines ever assembled and could have set multiple rushing records but he ran scared and never lived up to his potential.
Curry was disappointing but never really felt like he was or could be something incredible
Tate has also been very disappointing, the expectations were high coming out of ND as a Steve Smith type and big play ability, I think he has flashed some playmakers potential but hasn't been consistent enough, so I'd say he has been frustrating that he is getting a ton of reps and is not cemented himself as a consistent playmaker game in and game out.
