"He takes a lot of the beating off of Ryan [Clarke],'' Holgorsen said, referring to who is now the only experienced fullback on the roster. "If we only had one of them then Ryan would have a hard time making it through the spring. [Miles] is doing a good job of getting in there and taking 50 percent of those reps and just continuing to get better. You've got to learn what to do first before you teach them how to get better at it.''
"I've mentioned this before. He's a little bitty dude, but he doesn't play little,'' Holgorsen said. "He plays hard and he caught a couple of screens and he ran a couple of quicks and he caught a couple of balls [in Sunday's full scrimmage]. He did well.''
He's one of the five true freshmen who enrolled in January to get a head start. The 5-10, 196-pound defensive back from Orlando, Fla., might already have made enough of an impression to earn some playing time.
"Karl Joseph is probably the one guy out of all the new guys coming in that has got something to him,'' Holgorsen said. "You can pencil him in to play a good bit. He's mature, he's not scared and he's physical.
"Sometimes it takes guys a couple of years before they are physically ready to play or mentally ready to play, whatever it is. It was an easy adjustment for him. I'm not saying he doesn't make mistakes or miss tackles or any of that. He does. But from a demeanor standpoint, the effort and the maturity and the physical capabilities of being able to handle it, he's a guy that is going to be fine.''
"When he throws it, it goes exactly where you want him to throw it. It goes there and it looks good and it is usually extremely accurate,'' Holgorsen said. "That doesn't mean his eyes are always where they need to be. There's so much to think about from a communication standpoint. He's slow with it because he doesn't have the reps yet, but he's getting better at it.
"The one thing is that he stands in the pocket and he throws it and it goes exactly where you want it to go.''
