What seems to be the consensus among Chiefs fans (especially those over at Arrowhead Addict) is that drafting a left tackle would be a horrible move. Good reasons do exist behinds these thoughts, but I will do my best to debunk the myths surrounding drafting a LT. I hope to not be too repetitive of any others ideas, just throwing out more ideas.
1. Drafting a LT would upgrade a non-LT position on the O-Line with the Number 5 pick - This idea concerns drafting a LT then moving Albert to another position (probably LG). This idea only holds true if the LT drafted is no better than Albert. Although Albert may improve this next year, he is no proven commodity for the Chiefs. Brian Waters is also not a guarantee to stay around much longer. By drafting a LT number 5 overall, you would have to assume he is better than Albert (Pioli would have to believe this) and not just a little better, but significantly better. This then improves the LT position. By moving Albert to guard, you upgrade that position as well. That is two positions improved along the O-Line.
O-Line is a group commonly known for needing cohesion, chemistry, and time in order to mold into a formidable line. The better and more consistent your teammates, the better you become as an Offensive lineman. Thus by improving the LT position, and either the LG or RG position, the rest of the offensive line would become better too. Because the left side of the line is solidified and strong, protection can be shifted to the right, the players on the right side don't have to worry as much, and everyone gets better.
2. Upgrading the Offensive Line will significantly improve the Offense - This idea is the obvious one that most people use. Better protection, better running game, more time, better offense as a whole. This idea may be slightly underrated. The game takes place in the trenches, and with high draft picks established on the D-Line, it is the O-Line's turn. Albert was a first round pick, but he was a mid-first rounder, which is reasonable for a dominant guard. Jamaal Charles will find new found room, a bruising running back will be able to take advantage in goal line situations (a weakness for the Chiefs), and Cassel will have time in order to learn and progress instead of worrying about which way to run instead of throw. Cassel needs to get better, and other than a sure handed receiver, O-Line is the next best thing (and maybe better). The improvement of the Offense as a whole will take pressure off of the defensive side of the ball by having greater room for error and less time on the field.
3. None of the other top prospects are worth it - This is idea will be by far the most controversial of those presented here. A surefire LT (assuming Pioli believes thats what his highest rated LT is) provides more value than S, ILB, or WR. Eric Berry could be a dominant player, but no one knows if he will even be available. If he is, this article is much harder to write, but the safety position does not have the value that LT does. The problems with our safeties could possibly be blamed on a lack pass rush and other problems that may be fixed under Crennel. Also, safety could be drafted in the later rounds, and we need a SS (something I am not sure the 5'11" Berry is), not a FS. Although it may seems I am opposed to Berry, this is not so as I believe he could be the next best safety, but again, he may not be available. As for ILB (McClain), ILB is known to not be the most important position in the 3-4, and although McClain looks to be near perfect, he isn't. He has trouble taking on blockers and with coverage at times. Plus, a guy like Brandon Spikes maybe just as good and available in the 2nd. With WR none of the prospects this year really are top 5 picks and do not fit the speed profile needed by the Chiefs.
