While I am enjoying this year, Sam McKewon is very bearish on the offense for next year, and I agree with him. Sam expounds on this week's Pick 6 Podcast.
Burkhead had a chance to play with Helu, before taking over as the main RB. The WR's and TE's are going to have a lot of guys who haven't even seen the field that will need to contribute.
I love Morgan, but he's only one guy. Sam & Jon made some great comments on how they think DPE isn't a great receiver. DPE is a great talent at punt returner, but not a great WR.
