I wrote the following fanpost, right around roster cut time.  I thought I'd be interesting to revisit my predictions, see how close I was, and see what has changed.

After 5 games... my new short list of needs/changes to be made:

#1 OL... Replace Goff with Ndukwe or Alleman, get a backup OT on the active roster... NOW!!!!... Then, Draft a starting Center, and possibly a new LT (Okung, Baluga) or LG in 2010.

#2 Secondary... Not sure how to improve the current mess... but they HAVE to find someone who can cover a receiver for the rest of 2009... then DRAFT Mays or Berry!!!

#3 WR... They don't seem to be getting open.  Maybe design some better routes/plays... then CUT Copper or Engram in favor of Lance Long, and get Lawrence on the field!!!!

Thoughts???

Glaring need #1... Offensive Line

It's been very well documented that there were problems on this line for the last couple of seasons, and most felt that Pioli hadn't done enough to address them.  Well, I don't think you can make that argument now! 

By cutting Damien McIntosh, Herb Taylor, Daryl Harris, Tavarres Washington, Brian De La Puente, Eric Ghiaciuc and putting Colin Brown on IR... and trading for Alleman and Ndukwe...you can see that Pioli/Haley aren't just standing pat with an under performing line.

UPDATE :  O'Callaghan signed, Richardson cut.  More OL moves are surely on the way.

I expect Pioli to sign as many as 2 OT, and potentially a C. With 8 OL on the 53 man roster, and Wade Smith being "upgradeable", they could also cut from another position to create space for more OL depth.

the depth chart would be Albert/(FA to be named)... Waters/Wade Smith...Niswanger/ Alleman...Goff/ Ndukwe...Richardson/ (FA to be named) Ndukwe/O'Callaghan O'Callaghan/ Ndukwe

UPDATE : No moves at OT since O'Callaghan... though he's starting now and playing well.  Depth is SORELY needed, especially with Albert getting injured.

NEED:  Cut or demote Mike Goff, Start Ndukwe or Alleman at RG.  Upgrade at C is still needed... but likely won't come before the 2010 draft

Glaring need #2...Wide Receiver/KR/PR

I have been saying for a while that I thought the WR corps was underrated and that no other acquisitions were needed.  That all changed yesterday, IMO.

By cutting Taurus Johnson, Rodney Wright, Ashley Lelie, Amani Toomer...the Chiefs have made a statement that they still aren't happy at WR. 

The depth chart looks like this now:  Bowe, Bradley, Bobby Wade, Lawrence, Engram, Copper.

Obviously, Bowe and Bradley are solid.  Lawrence has shown flashes of brilliance, flashes of butterfingers... but it's clear that the coaching staff sees plenty in him, and he factors into the plans in a big way. 

The two questions in my opinion are Engram and Copper...they could easily be replaced and upgraded.  In my opinion, a young slot receiver that can return kicks (like Lance Long, or Edelman in NE) would be the best upgrade to this group of WR.  A home run hitter/big name Wide Receiver would be a second priority this year, but a top priority in the draft next year.

UPDATE : Bobby Wade was signed, and has played reasonbly well.  Bowe has played well at times, but receivers getting open seems to be a problem.  Lance Long was added to the Practice Squad.

NEED: Quickness and separation... Lance Long may be on his way to the active roster soon, at the expense of Bobby Engram.  KR/PR have been mediocre, but (again) I can't see an upgrade coming before the draft.

Glaring need #3... Tight End

I've said before that KC fans have been spoiled all these years with TG and Jason Dunn.  For years, we could count on one TE catching everything in sight, and another acting as a snowplow for RBs and as a 6th offensive lineman for pass protection.

Pioli/Haley obviously value the TE position differently than the prior regime.  They traded Gonzalez for a 2nd round pick, then brought in Sean Ryan and traded into the 7th to draft Jake O'Connell.

My prediction:  The Chiefs could very likely be looking to bring in a TE like Pope, Smith or Watson.  My vote continues to be for a great blocking TE, wherever they can find one.  I think they'll keep 3 TE on the roster, so O'Connell could be the odd man out if an acquisition is made... but don't be too shocked if they cut Cottam at some point.

UPDATE : Leonard Pope has signed, and is playing.

NEED: There seems to be an extra TE on the roster... Cottam or O'Connell should be off of the active roster soon.

Not-so-glaring need #1...Fullback

Mike Cox has been a serviceable FB for the Chiefs... but he's definitely a "Chan Gailey" guy.  Pioli and Haley have no reason to be loyal to Cox, as they look over the list of free agents and waived players.

My prediction:  Dan Klecko could be brought in to replace Cox.  He's huge and versatile, and was drafted by Pioli.  This could be a nice upgrade. 

UPDATE:  no news... Cox is ok, no one has been signed.

Not-so-glaring need #2...backup QB

My prediction:  The Chiefs stand pat with Croyle and Gutierrez as the backup QBs.  Thigpen is traded if they can find a taker, or cut as soon as Cassel is healthy enough to play.  They'll need the roster spot to upgrade OL and WR.

UPDATE : Thigpen was traded for an undisclosed draft pick. 

NEED:  None.  Cassel, Croyle, Gutierrez is the depth chart, and that's solid.

Not-so-glaring need #3... Safety

The secondary should be a strength for this team, but coverage has been soft, and turnovers have been scarce.  The fans all said KC was set in the secondary, but the new management has shown their dissatisfaction by cutting Pollard, signing Mike Brown and drafting Donald Washington.

My prediction:  The Chiefs could bring in a safety that is known to be great in coverage and a ball hawk.  If so, Ricardo Colclough is the next likely cut in the secondary.

UPDATE : Colclough was cut, but no Safety has been brought in.

NEED:  This is now a GLARING need.  Both Safety and CB (after Flowers and Carr) have had all kinds of trouble in coverage.  Not sure what can be done this year, but the case for Berry or Mays in the draft is getting stronger every week.
