I'm not high on rookie WR. They traditionally do poorly compared to other rookies. That said, I keep hearing that the Vikes plan on using Patterson similar to the way they used Harvin. I think they get him more involved in the offense. And if this is an IDP league, he'll get credit for tackles too when the ball is turned over (ok, that was cold).
Te'o I'm not very high on. He is nursing an injury. But he should get plenty of chances to make tackles if the Bolts do a lot of 3-and-outs. But will he make the tackles?
Meanwhile, the Ravens lost a few guys this year (like Lewis, Kruger, Pollard & Reed) which should really give Brown a decent shot.
If I were to adjust my list I may put Brown above Patterson, but Te'o is still 3rd.
LOL, no worries, I feel you man. I'm learning new stuff every year. I think the whole IDP is a reasonably new thing, like last few years, at least in mainstream formats. I'm sure there are hardcore dudes who have been using them for many years.
