Turnover is an annual tradition in college football, but with that, teams' strengths and weaknesses constantly shift, too. Today, we'll continue our look at the biggest strengths and weaknesses for each Big 12 team.

Next up: Oklahoma State.

Strongest position: Pass-catchers

I'll have to apologize to Oklahoma State's trio of safeties in Daytawion Lowe, Shamiel Gary and Zack Craig here, but I'm going with the guys hauling in balls in OSU's pass-first offense as the strongest position. I don't care to debate whether Blake Jackson is a receiver or a tight end (he's the former), but I'm obviously including him in this group. He'll be an interesting guy to watch this year after struggling with drops but clearly possessing loads of potential and averaging better than 20 yards a catch on his 29 grabs.

Oklahoma State had nine players with at least 12 catches and 150 receiving yards last season and returns six of those players, including Tracy Moore, who was given an extra year of eligibility. He won't be joined by Michael Harrison, who sat out 2012 and was expected to return, but won't be doing so after a strong 2011 season under Justin Blackmon.

Somehow, we've gotten this far without mentioning the unit's headliner, breakout star Josh Stewart. He was overshadowed by a trio of superstars in Baylor's Terrance Williams and West Virginia's Tavon Austin and Stedman Bailey, but all three are gone and Stewart is easily the Big 12's best returning receiver. He caught 101 balls for 1,210 yards and seven scores last season, which is more than 150 yards more than any other returning receiver in the league. Stewart's underrated for now, but that could change soon, even though Oklahoma State has a ton of depth at the position with guys like Austin Hays and Charlie Moore filling out the position and Blake Webb emerging late in the season. Will incoming freshmen like Ra'Shaad Samples and Marcell Ateman find space to make an impact right away? It won't be easy, because this is Oklahoma State's biggest strength.

Weakest position: Defensive end

I've got nothing against juco transfers, who can walk on campus and be game-changers immediately, but if you're bringing in guys to do that, it shows a weakness at the position. Oklahoma State is doing that with Sam Wren, the nation's No. 16 overall juco prospect, after the Pokes lost three defensive ends from last season's team in Nigel Nicholas, Ryan Robinson and Cooper Bassett. Tyler Johnson is a solid player who made six tackles for loss a year ago, but OSU needs to find him help on the other side or opponents will be able to shut him down with double teams. Kansas State's Joe Bob Clements is a new addition to the staff who'll coach the position and try to sort it out this spring, but look for guys like Trace Clark, Jimmy Bean and early enrollee Naim Mustafaa to try to earn a starting spot, too.

More Weak and Strong.
