Ultimately, it may be Jake Wise, the starter the last two years and expected to be in pro ball by now except for a torn ligament in his elbow that forced "Tommy John surgery" over the summer.
Wise is back for his senior season because of that rehab. He's ahead of schedule but it's still doubtful that he'll catch much in the first month of the season, instead probably serve as the designated hitter.
While Wise concentrates on swinging the bat and playing a big role in leadership, some young catchers will battle in fall practices to earn playing time in the early months of the season and perhaps make Wise a DH more often during the season.
"He's come back with a tremendous attitude," Van Horn said. "He's swinging the bat outstanding right now. He's been bouncing around and leading."
Blake Baxendale, the 2012 player of the year in Arkansas, is healthy after undergoing Tommy John surgery last November, but he will be pushed by a pair of newcomers, Carson Shaddy (Fayetteville) and Alex Gosser (North Little Rock).
"I think Blake learned the program and what's expected of him being a catcher," Van Horn said. "He knows if he goes out and catches well and throws well, that's the top priority. If they hit, that's a major plus.
"It helps him that he's been here and he knows the pitchers' stuff a little bit. Just being in the program an extra year, that helps."
The evaluation process will be going on big-time at spots other than catcher after the Hogs lost regulars in the outfield and the mainstays of perhaps the school's best-ever pitching staff, including high draftees Ryne Stanek, Colby Suggs and Barrett Astin.
"We've got new players, a couple of new coaches, but still the same hard-working attitude we've always had," said Van Horn, who is entering his 12th season as the Razorbacks' coach. "I think it's good every now and then to inject a little bit of energy and life into your program, and maybe a little different philosophies as far as offense and different things.
"I think the players are smiling and working hard, and I've seen some pretty good leadership from guys who have been in the program a few years.
"Last fall we wanted to get better obviously, but we wanted to make sure nobody got hurt. I think this fall is a lot more about evaluation and trying to figure out some positions, and maybe even the batting order. This fall is going to be very competitive for us."
Arkansas has a 45-day fall practice window. The Razorbacks will practice 28 times as a team, culminating in their annual Red-White series at Baum Stadium.
A total of 11 players were taken in the MLB Draft in June, with 10 opting to sign professional contracts. Only first baseman Eric Fisher decided to return to school after being drafted, leaving Arkansas with several voids to fill this fall.
In particular, the Razorbacks will be looking to replace the bulk of a pitching staff that recorded the NCAA's lowest earned run average in nearly four decades a year ago. All three weekend starters are gone, as are a handful of ace relievers.
Van Horn is looking toward a pair of sophomores to lead the pitching staff next season. One of those is Colin Poche, a left-hander who turned down a fifth round offer from the Baltimore Orioles in 2012, was rated the top prospect in the Northwoods League by Baseball America after a solid summer on the mound.
"I'm not going to say it's the best league in the country because Cape Cod League is pretty darn good, but it's a good league and he went up there and did what he needed to do," Van Horn said. "He threw a lot of strikes and got better.
"Hopefully he's turned the corner and knows he'll take some responsibility."
The outfield looks more potent at the plate, perhaps giving up a little defense in centerfield with the arrival of Andrew Benintendi, the likely replacement for Jacob Morris and Matt Vinson, two flyers who split time there the last two seasons.
Benintendi, 5-10 and 170, was the National Gatorade Player of the Year last year after batting .564 as a senior at his Cincinnati area high school. He was not known as a flyer and doesn't have the size of Morris or Vinson.
"But he's faster than I thought," Van Horn said. "He runs very well. He kinda glides out there in center. He's very good in the outfield, a natural centerfielder. If he was 6-2, he would have been highly drafted. And his bat is as quick as we thought."
Benintendi is expected to bat high in the order, perhaps leadoff, unless his lefty bat holds too much power to keep out of the heart of the lineup. Van Horn knows he'll have Tyler Spoon, Brian Anderson and Joe Serrano high in the lineup, too.
Spoon will join Benintendi in the outfield, possibly with by redshirt Garrett Rucker, who had a hot late summer after a slow start, much like Spoon in 2012.
"Garrett put on weight and after a horrendous start this summer, he made a jump in the second half," Van Horn said. "He hit home runs and the ball jumped off his bat. He's a lot stronger.
"He was a quarterback at Arkadelphia and we liked him coming in, but he seemed too passive. We hope to see a lot more confidence this fall."
The top returning hands in the infield are shortstop Brett McAfee, steady down the stretch last year, and first baseman Eric Fisher, solid in the regional and back from an impressive summer.
The battle at second could be interesting where both Anderson and Serrano have worked, both with good results so far. Anderson wants another try at the infield after altering his grip for summer ball.
"Coach (Dave) Jorn figured it out," Van Horn said. "He'd made so many errors throwing and Dave just asked to see his grip. It was a three-finger and a thumb, the way you hold it when you first start playing. It usually gets changed by Little League.
"He's gripping it right now, two fingers and a thumb. the ball was coming out of his hand and sailing. This should help."
Anderson has mentioned trying to help as a pitcher and that might get a look in fall ball. He was a high velocity pitcher in high school, but came to school with a sore arm and that was put on the shelf. It's healthy now.
"We've worked Anderson at a lot of spots in the infield, but hard at second," Van Horn said. "Serrano has made a major jump at second. He played infield in high school.
"We thought McAfee did a tremendous job the second half of the season. Overall, we tried to shore up the defense. We have got to play better defense."
