We'll see. I remember thinking Beachum wasn't NFL material when we took him, but he acquitted himself well (or well enough) in spot duty. I think he's a solid backup at both OG spots and maybe RT. LT is a whole other creature, though. From an old Finny draft guide on OTs:
Generally, OTs need to be 6’5” or taller, with shorter OTs plugged in at OG. Marvel Smith was a shade under 6’5”, for a point of comparison. I’ve seen collegiate tackles listed at 6’3” on the NFLDS OT lists, and I’ve moved them to my OG lists. For LT, you cannot be slow and be effective. Period. That means the much-despised Indy combine 40 time actually makes a difference in how quickly a big guy on the edge can kick out. My arbitrary numbers are 5.20 as potentially competent LT, and under 5.10 for possible elite LT. The player must obviously have skills – the ability to use his hands properly, to bend and use leverage, to understand blocking schemes – but players who can’t trot the 40 in under 5.20 seconds start to suggest RT only.
At the time, I believe I just casually noticed the correlation between 40 and LT success, but let's look and see if that's true. I'd say the following are the best 10 LTs in the league (when healthy):
1. Duane Brown - 5.03-5.07 40 time; a little shorter than my guidelines at 6'4", but as noted height is not the prime driver.
2. Joe Staley - 4.79; 6'6"
3. Russel Okung - 5.18; 6'5"
4. Joe Thomas - 4.92; 6'7"
5. Ryan Clady - 5.18; 6'6"
6. Andrew Whitworth - 5.16; 6'7"
7. Michael Roos - 5.15-5.30; 6'7"
8. Eugene Monroe - 5.18' 6'5"
9. Trent Williams - 4.88; 6'5"
10. Nate Solder - 5.05; 6'8"
Summary: 10/10 LTs clocked times <5.20 (combine or school workout); 9/10 meet frame requirement of 6'5" or taller. I'll add another, which I had previously never used because tall guys with long arms aren't going to rock the bench press: 20+ reps at 225#. I noticed that of these LTs, none repped more than 30 (Thomas got to 28), but 9/10 repped more than 20 (Roos came in at 19).
So, let's compare.
Kelvin Beachum - 5.44; 6'2"; 19 reps. Small and weak are really sideshows to how slow Beachum is. IMO, destines to fail. Of course, I thought the same of him at OG, but as they say, apples to oranges, especially kicking out to the blind side.
Mike Adams - 5.40; 6'7"; 19 reps. Hey, he's tall. I think my comments on Adams at draft time were along the lines of slow, weak, smokes pot, so pass. Getting off the weed didn't suddenly make Mikey fast though.
Marcus Gilbert - 5.41; 6'6"; 30 reps. Third of three without foot speed. Has some weight room strength, not sure I've seen it translate to the field. Seems to be RT-only.
WRT to LT, destined to fail.
Oh wait, we also have:
Levi Brown - 5.40; 6'6"; 31 reps. Thus continuing our penchant for abysmally slow LTs. Or, what the rest of the league refer to as RTs. Workout numbers suggest he is essentially Marcus Gilbert, which is what game film suggests as well.
Stocked to the gills with RTs, no LT anywhere to be found. There are some great WR candidates in the top 10 of the 2014 draft, but I would suggest we consider LT. For once. FFS. Just once.
