I don't think anyone disagrees with you about anything you just said. It's just that we DID carve out a role in the offense for Jamal - that's why he was the team's leading receiver halfway through last season, even though he didn't know the playbook or the position very well. Then he started underachieving - he dropped passes, he was dogging it in practice, he struggled with blocking, and Marlowe beat him out for the job. And while he doesn't need to have a QB-like command of the offense, he does have to know how to get lined up right. The coaches didn't even trust him to do that in the latter part of the 2011 season, so he didn't see the field so much as the coaches opened the offense up more in conference play.
Anyways, it's his second year in the system, his second year at the position, and we should see clear improvement from him. I think the offense as a whole is very promising - unfortunately, the biggest question marks are again on the o-line.
I personally can only remember 1 dropped pass at the end of a blowout. There might have been another 1 or two, but it's not like he was dropping passes left and right. Both Kinnie and Bell dropped far more than Turner, yet they were on the field the entire season.
And I find it hard to believe that he had no issues lining up the first half of the season...then with 3 months and 7 games under his belt he all of a sudden couldn't be trusted to line up in the right spot.
Kinnie and Bell were more complete players though. They knew the whole offense, and they can block. The only reason to have Jamal on the field last year was that he was such a playmaker that he needed his touches - but if he's a liability to drop the ball when it gets thrown to him, his playmaking ability is useless. If he can't get lined up right, same thing.
If you only have one or two packages you play in, like Jamal did last year, you better damn well execute when you get your chance. If you get your chance and blow it, like he did, then expect to see guys who are more complete players, who can contribute in a variety of ways.
Furthermore, just because you remember only one dropped pass in a game doesn't mean it wasn't an issue in practice. Remember they created the "Jamal Drill," to address dropped passes, and there were multiple stories where Jamal himself admitted that he was dogging it in practice. I don't care if we have the next Randy Moss - if the kid is dogging it in practice, he sits. End of story.
