Looking at this from a distance, you're asking me to believe that both teams used their extremely valuable pick simply to save a little money instead of getting an elite player or fill one of their grocery list of holes?
To answer your question as you phrased it would require me to buy into your contention that there weren't better players available. I don't buy that. Although I must say that I didn't do much research on players I didn't think we'd want to draft.
Look at the needs for these two teams according to SB Nation.

Kansas City Chiefs 2013 Top three needs
Inside linebacker - Derrick Johnson is a fine inside linebacker, but the Chiefs need another one to help stop opposing runers.
Defensive line - The Chiefs lost Glenn Dorsey, but managed to hang onto
Tyson Jacksonat a reduced rate. Another defensive end capable of generating pressure is a must.
Dontari Poe did well against the run last year, but brought next to nothing in the way of penetration.
Offensive tackle - Kansas City cut
Eric Winston, last year's starting right tackle, and seems to be on the verge of trading left tackle Brandon Albert. Even if Albert isn't dealt, he's likely to go after the season. They need someone to keep Smith on his feet.
Ideal pick: Luke Joeckel, OT, Texas A&M
All three of these players were available for the Chiefs but they filled one of their needs and RT was a huge need:
Sheldon Richardson DT drafted #13
Star Lotulelei DT drafted #14
Jarvis Jones LB drafted #17

Jacksonville Jaguars 2013 Top three needs
Pass rusher - The Jaguars ranked last in the league with only 20 sacks last year. For years, the team has attempted to bolster the pass rush, drafting
Derrick Harvey in 2008, signing
Aaron Kampman in free agency back in 2010, and most recently signing
Jason Babin after he was waived by the
Eagles. While Babin and last year's second-round pick
Andre Branch provide some hope, the team can't afford to pass on some of the elite talent available at the position towards the top of this draft.
Cornerback - After letting
Rashean Mathis and Derrick Cox walk in free agency, the Jaguars have a depleted cornerback depth chart. While the team isn't likely to draft the position with the No. 2 pick, cornerback depth will likely be a priority on days two and three.
Quarterback - With
Blaine Gabbert and
Chad Henne as the only two quarterbacks on the roster, Jacksonville has to add a signal caller at some point on draft weekend. Thus far, neither Gabbert or Henne has inspired a ton of hope, so the Jaguars could look to address quarterback sooner rather than later.
Ideal pick- Dion Jordan, DE/LB, Oregon or Ezekiel Ansah, DE, BYU
All five of these players were available for the Jags that could have been used to fill huge needs:
Dee Milliner CB drafted #9
D. J. Hayden CB drafted #12
Dion Jordan DE drafted #3
Ezekiel Ansah DE drafted #5
Barkevious Mingo DE drafted #6
On the other hand, many
pundits don't think the were many elite players not at OT available in the draft but I've yet to hear that from a GM. So you have that going for you but I still think you're projecting your own evaluations of players into your viewpoint here.
