Geoff Swaim was quietly one of the best players for Texas in 2014 and some scouts were so impressed by his blocking ability that they said they'd draft him to play OL were he a bit bigger.
Texas fans noticed him mostly for dropping some passes against Oregon in the 2013 Alamo Bowl but he was a brilliant blocker that made the run game go for two consecutive seasons. Texas doesn't seem to have any TEs on the roster who are ready to replace him, so they're going to have to use Daje Johnson.
That's right, 5'10" 178 pound Daje Johnson is the best answer for how Texas can replace the production lost when Swaim graduated and departed to the NFL. Read about it here.
