Have you watched him in the games? Did you watch preseason? He cannot catch. Balls hit him in the hands and he routinely drops them. He has had some issues on some routes as well. He does a decent job on special teams, but is not worthy of a roster spot. Why force feed a 29 year old bad player? He is not a player that is young and developing at this point. Just like Stills, he is pretty much done.
Yes, I have watched him. And 5 pass attempts, possibly none that were easy catches (going by memory) because they were all down the field. That's just not enough for me. The two slants in the preseason were terrible drops but he literally just joined the team and I'm sure he was pressing too much, as he probably thought he needed to make a splash to just make the final roster. Possibly the only chance he was going to get.
I know that sounds like excuses, but outside his first year on the Bears, he has never had even 10 passes thrown his way in a single season. That's simply not "plenty" of chances. So why force feed him? Why not? Where is this offense going that you can't afford to throw even 6 passes his way in a game? They threw 22 to Stills in total and 5 to White. This offense isn't good and the team is likely to miss the playoffs so you might as well try something instead of sticking to what hasn't worked.
Now, maybe the most damning thing against White - it's definitely not his two preseason drops or his drops so far this regular season - is that he was cut by the Bears, Cardinals, and 49ers. And now on the Saints it seems he really hasn't made enough of an impression for them to think they have to get him the ball. So possibly in practice, when he's got the coaches eyes on him, he's simply not impressing. Might very well be true, and this might be his biggest issue. But I'd still like to see a half dozen or more passes thrown his way in a game. I'd tell him to relax, we'll get the ball to you a bunch of times, and if you drop passes guess what? We'll still throw to you. Try it for a few games and see how he does. If it's drop city then cut him and don't sign him again.
But for this to work, if it has even a slight chance, you clearly have to throw him higher percentage passes and try to have him relax and not worry about dropping the ball (which all WRs in the NFL do, on pretty much a weekly basis).
I just don't get why teams sign a guy like White, with his pedigree, to not throw to him and play him on special teams, all while throwing it over and over again to guys we all know aren't ever going to be great.
