Some fans seem to be overrating the impact of Xanders given the relatively successful Lions draft in 2013. Stop!
Correlation is not equal to correlation. If Xanders leaves, and the 2014 draft is not as successful as 2013, it will probably be due to a number of factors that have nothing to do with Xanders.
Granted Xanders helped with how they signed UFAs, so he should get some credit for helping to get Fauria and Waddle. But the signing advice he introduced will most likely still be used once he leaves.
1. They had two extra draft picks in 2013. That helps. Not clear that will be the case in 2014.
2. They had a high draft position. Will be lower in 2014.
3. They coached the Senior Bowl. Won't be in 2014. Three of their draftees were coached by them at the Senior Bowl. Also helped them figure out which players NOT to draft.
4. 2013 was an overall deep draft, as most draftniks will acknowledge. 2014 is supposedly not as deep as 2013.
Look at the 49ers 2012 draft vs. 2013. Nothing to do with Xanders, but their 2013 draft was great because there were many more good players in 2013 vs 2012:
2012: A.J. Jenkins (major bust), LaMichael James , Joe Looney, Darius Fleming, Trent Robinson, Jason Slowey, Cam Johnson
2013: Eric Reid, "Tank" Carradine, Vance McDonald, Corey Lemonier, Quinton Patton, Marcus Lattimore, Quinton Dial, Nick Moody, B.J. Daniels, Carter Bykowski, Marcus Cooper(starting CB for the Chiefs after being cut)
Way more important contributors for the 49ers from the 2013 draft than in 2012. And Carradine and Lattimore could be beasts once they get healthy.
5. Look at the picks one by one:
Rd 1: Ansah - Coached at the Senior Bowl. Hard to argue this was a Xanders pick.
Rd 2: Slay - Jury is out on him. But fit the profile of long, fast corners that Gunther was looking for. Also hard to argue this was Xanders
Rd3: Warford - Coached at the Senior Bowl. Hard to argue this was also a Xanders pick.
Rd4: Devin Taylor - Fit the profile of the a Jason Jones-type DE that was tall and fast with long arms. Hard to argue this was a Xanders pick vs a Schwartz/Gunther pick, given that Gunther did a study of arm length vs sacks during the offseason.
Rd5: Sam Martin - Bonamego spent a lot of time with this guy evaluating him. Would give credit to Bonamego rather than Xanders.
Rd6: Corey Fuller - Practice squad. Irrelevant thus far.
Rd6: Theo Riddick - Curtis Modkins pushed for him due to Notre Dame connections. Watch the original press conference by Modkins on Riddick on the Lions site.
Rd7: Michael Williams - Coached at Senior Bowl. Bobby Johnson (TE coach) pushed for him. Watch the original press conference by Johnson on Williams on the Lions site.
Rd7: Brandon Hepburn - Practice squad. Irrelevant thus far.
So going through these, it's really hard to say that Xanders was instrumental in any of these picks. 2013 was just a deep draft overall.
