I wouldn't sweat the kid's 40 time. Moeaki had some timed 40s around 4.7 and 4.8 .... and most folks had him pegged as an elite 5-star TE. Most high school players have a lot of wasted motion when it comes to their timed 40s. Unless a kid really works the combine and camp circuit ... they're typically not very refined in how they run their 40. Thus, 40 times don't always look pretty from such guys. However, what matters more is whether the kid pops out on tape ... and from everything I've heard, Beyer sounds like he's a versatile athlete who could develop at several positions for us.
The 2016 class is pretty fascinating because we've landed so many "taller" versatile athletes. Welch and Niemann are both taller and "faster" OLB-types ... however, both guys also could project at TE and DE. Golston is a versatile "taller" guy .... he seems to me like he could potentially land somewhere in-between Riley Rieff and Matt Nelson. He could remain at DE ... or he could potentially grow into a stud OT. Anyhow, I love how his high school coach raves about what a team player the kid is ... really is a jack-of-all-trades sort of player (does anything the coaches want him to ... and he does it well).
Beyer and Fant are both versatile guys who project well at both TE and DE. Hockenson may be versatile ... but I see him slated as TE all-the-way. The great news is that the TEs are going to have A LOT of competition in the room through the next several years ... and that will only make the guys better!
McKnight is pretty much the only DE recruit who really seems to "only" project at DE. The two other guys, Lattimore and Schulte, both seem like they're the types who could end up at either DE or DT. It sounds like Lattimore is an athletic freak ... who will be about to play inside or out ... maybe akin to a Christian Ballard or Jonathan Babineaux. Schulte seems like he could be somewhere in-between a Matt Kroul and Jared Clauss-type. Given the injuries to McKnight and Schulte ... they'll likely start off as "developmental" projects ... but such projects tend to turn out well at Iowa.
