These last two weeks, we've been looking at the biggest shoes that need to be filled on every roster in the Big 12.

We continue the series below with the Texas Tech Red Raiders.

Wide receiver Jakeem Grant

Texas Tech's record-breaking receiver was one of the most dynamic playmakers in the Big 12 last season. Not only did Grant break the Tech single-season record for all-purpose yards and career receiving yards, he finished fourth nationally in all-purpose yards.

The All-Big 12 slot man won't be easily replaced. In the open field, he was one of the most difficult players to tackle in the country, and was a threat to go the distance at any moment, including on special teams.

The Red Raiders don't have a player coming back or coming in who possesses the explosiveness Grant did. But with quarterback Patrick Mahomes returning, that doesn't mean Tech won't be lethal offensively again in 2016.

Tech figures to lean even more on rising juniors Ian Sadler and Cameron Batson, who have played key roles in the rotation over their first two years on campus. The two combined for 71 receptions, 923 receiving yards and four touchdowns last season. Walk-on Zach Austin gave the Red Raiders a boost from the inside as well last season, most notably a 110-yard receiving effort against Baylor.

ESPN JC50 receiver De'Quan Bowman, the No. 31 overall juco recruit, should help the Red Raiders right away, too.

Individually, none of the above are Grant, who will go down as one of the finest receivers in Tech history.

But collectively, with a couple of proven players to go along with an intriguing juco signee, Mahomes should have plenty of options from the inside receiver spots to throw to again next season.
