So, let's take a look at OL and WR recruiting for the years that should give us Seniors and Juniors and see what happened (listed name, position, recruiter according to Rivals)... Feel free to add thoughts, they are off the top of my head

I am not sure who the "evaluators" were who decided to go after the different players, but we can see that from the OL recruited, only 3 out of the 16 have made any impact, and one of those 3 struggles. There are a ton of misses here, so whomever does our OL evaluation has done a poor job. Klemm's name actually isn't on here very often because he was really only associated with the last class on this list; his other recruits were underclassmen. It seems like Burns, McKnight and Reinbold were responsible?
As for WR, 13 recruits, and all 4 current starters fall into this list. 2 never did anything, 1 injury issue, and then 4 of the highest rated recruits had grade issues and weren't here for long, if at all. The other two (loftin and holyfield) are backups. Odum and Reinbold were the ones recruiting here, and it seems like there are just a lot of risks taken for academics who never got in, or just trying to get some athletes who might be hidden gems.
All-in-all, it seems like our WR eval and OL eval was pretty poor for several years.We may have taken too long to do something about it. I know for evaluation, they have people responsible for postiions, who bring players to the larger group, and the larger group decides who to offer. We made a pretty quick move to change the evaluation procedure at OL, by bringing Klemm in after 2 years, but it seems like we waited too long to modify the WR evaluation, and that is probably on Jones as the head of the organization.
