I mean, the thing is, UK really ISN'T bereft of talented linemen anymore.  We're bereft of talented EXPERIENCED linemen.
Our struggles in the future, talent-wise, look to be on defensive line, linebacker, and offensive tackle.  We've got plenty of wideouts, defensive backs, running backs, and guards/centers.
I totally agree that if we have a spot for him that doesn't need to be taken by DT/DE/LB/OT, we should offer him.  But if we don't...well, you gotta recruit to your needs.  Especially when you don't intend to sign a 25 or 28 man class.
		
		
	 
When looking at the current roster, there is no more depth for 2016/2017 on the interior OL than elsewhere.  However, there will be considerably more FR/SO bodies at DB/LB than OL/DL.  That's my cutoff b/c Bentley (or any other 2017 OL/DL recruit) would probably be played prematurely prior to 2018. 
Let's look at the current project depth chart for 2018
OLINE
OT - Landon Young (tr JR or RS SO)
OG - Stenberg (JR)
C - Stallings (SR)
OG - GAA (SR)
OT - Wolfe (JR)
Backups - OG Fortner (SO), OG/C Drake Jackson (SO), OT - Dotson (RS FR), OT/OG Wills (hopefully - RS FR or SO)
DLINE
DE/DT - Kengera Daniel (SR), Taylor (JR), TJ Carter (SO)
NT - Dubose (SR), Cross (SO), Bohanna (FR)
DT - Middleton (SR), Looney (SO), Hudson (FR)
I still wonder if Calvin Taylor sticks at DL or moves to OT (maybe lacks lateral quickness for OT?)  If he has developed in JUCO and can graduate in December, I'd love to see Provitt added for NT for the 2017 class, then he'd add another SR at NT.
Honestly, LB/DB looks stacked w/good depth.  So, if anything, I'd take only one at each of those and add to all OL/DL positions.  Plus, it's typically easier to throw FR/SO in at LB/DB than along the lines.
LB
OLB/Jack - Ware (SR), Bonner (SR), Bannerman (SO), King (FR)
MLB - Kash Daniel (JR), Firios (SR), Walder (SO)
WLB - Jordan Jones (SR), Eli Brown (JR), Watson (SO), Jamin Davis (FR)
SLB - Allen (SR), Walker (SR)
DB
CB - Westry (SR), Tucker (SR), Robinson (SO)
S - West (SR), Marcus Walker (JR)
S - Edwards (SR), Gilliam (SO)
CB - Baity (SR), Beckham (JR), Griffin (SO)
CB/S - Ajian (FR)
Considering how much longer it takes to develop OL/DL, I would definitely focus efforts there for 2017.  I think you could probably take zero LB/DB in 2017 and add any OL or DL position. To clarify, I'm not pushing for Bentley specifically but only the argument that EVEN WITH a small class, there is no OL or DL position that has so much depth as to not need a recruit in 2017
