re: What are the current missing pieces to our team that would win us a championship?

LT, DE, LG, K, TE......In that order
--LT: A competent LT would Carr more time & confidence in the pocket to be a better passer without rushing himself.
--DE: An end with legit pass rush ability could really open up our D on obvious passing downs. At this point Cam is still no slouch and still has a good motor/hustle, but I don't see opposing OCs fearing him or gameplanning around him. Use Danielle Hunter as an example since he was rumored available recently then sliding Cam inside next to Bresee and Granderson on the other end. Cam & Bresee still have enough size and ability for the occasional runs on those downs too.
--LG: Same as LT, improvement in pass protection or run blocking would be immediately beneficial
--K; Groupe struggling as a rookie undrafted shouldn't be a great surprise to anyone. He's been "okay" but could be much better. Perhaps he turns into that guy, but a higher % kicker could probably have us 6-3 instead of 5-4, but fixing the above positions first should have a greater impact in my opinion
--TE: Have not had much production through 9 games from our 4 TEs, perhaps Juwan coming back healthy now will change that
