Alexander:
27/105/1 in a win against Tampa, who looks very good defensively
18/70/1 in a close loss against Arizona, who looks improved defensively
21/100/0 in a close win against Cincinatti, who looks bad defensively.
25/78/0 in a blowout win against San Francisco, who looks mediocre defensively
11/25/0 in a blowout loss against Pittsburgh, who looks very good defensively
Nothing worked well for the Seahawks yesterday. Otherwise he has looked good. 415 total yards and 2 TDs through 5 games isn't great, but he's faced some tough defenses and was looking pretty good until yesterday. Sure he hasn't had that 2 TD game, but he's had a couple of 100 yard games, and a couple of TDs, and that's pretty decent. Through the first four games, he was on pace for a 1500 yard, 8 TD season. He got shut down in a blowout loss but also plays some soft defenses soon. No reason to think he won't be good the rest of the way.
I don't own him in any money leagues, but I may try to acquire him if this is really how people feel about him right now.
