You joke, but I'd take Bohannon over a heck of a lot of other PGs. Gesell and Clemmons were both solid. Marble, if you're willing to consider him a combo guard. Connor has yet to be seen, but attrition at guard was brutal last year. As for defense, here is team defensive efficiency:
2019 - 54? <-insert Connor and Wieskamp here (ranking jump of 254 spots from 2012 to 2013)
2018 - 308 <-Lose top 2 backup point guards, Baer hand injury out for 1 month, no upperclassmen
2017 - 200 <-All freshman team
2016 - 76
2015 - 40
2014 - 60
2013 - 33 <-insert Woodbury and Gessel here
2012 - 287
2011 - 151
I'm not saying it will happen, I'm just saying there's precedent for major improvements in team defense year over year. We like to poke fun at it on the forums, but for a guy who prides himself on being a fast paced offensive coach, he has the stats to back up being a good defensive coach too.
