We tend to forget about the offensive line when talking about the skill position players. Martin could be a solid three year starter at tackle and provide a great anchor for the line in years to come. Great choice.
There is too much depth, at the moment. There are more experienced receivers in front of him that have a better grasp of route running, getting off the press, etc.
I personally believe Theo will have his "breakout year" at receiver in 2011. Floyd, Kamara, Evans, Jones, Goodman, Walker? That's some tough competition. Once Kamara (and possibly Floyd) leave after this season, that's when Theo makes his impact. It's looking like the starting three will be Floyd, Kamara, and Jones. Theo will make it in the rotation, but I don't think we'll see the production everyone is predicting until 2011, when Theo has more opportunities and a year of receiver experience.
