Irby was an all-state selection who also participated (at linebacker) in the U.S. Army All-American Bowl in January.
Listed at 6-4, 210-pounds, Marshall is probably a step slow compared to Texas' fleet of current receivers. Clocked at 4.5, Marshall comes closer to fitting the profile of stretch-the-field TEs that has been featured in the Texas offense the past three seasons.
"Bo Scaife and David Thomas were both slot receivers," Davis continued. "You take a guy like Josh who runs really well for a tight end and put him outside in a press situation, he runs okay. Moving him inside gives us the opportunity to continue to do the things we've been able to do with our tight ends.
"I might not have that top speed where I can blow people away," Marshall previously told Inside Texas, "but I'm quick to where I can get on them pretty fast and do what I've got to do. I have great hands and I can run nice routes."
The current depth chart would list sophomore Jermichael Finley with the Ones with junior Peter Ullman as his primary backup. Finley is a chiseled freak and is listed at 6-5, 236-pounds, but told Inside Texas on Monday that he's up to 245. (Imagine Vince Young's frame with 20 extra pounds of lean muscle). Finley accounted for 372 yards on 31 grabs during his RS-freshman campaign. However, he became more of go-to guy during the latter part of the season as more than half of his catches (16) came during the final four ball games.
Ullman is a fourth-year player who has appeared in 24 games. The 6-4, 255-pounder's strength is obviously blocking and will be primarily counted on in jumbo packages. He does a TD-reception to his a credit when he scored on a two-yard pass against Kansas in 2005. RS-freshman Greg Smith (TE) has not participated in spring drills.
Otherwise, there have not been any other major changes in personnel, Davis told Inside Texas. Said Davis: "Chris Ogbonnaya has been working at both fullback and tailback. Antwan Cobb is working at fullback. But, nothing else in terms of moving a guy from wide receiver to tight end."
The Horns are currently in the final week of spring football. The annual Orange-White scrimmage is set for noon, Saturday at Royal-Texas Memorial Stadium.
