I trust in JMac, but just like the DL that bolted after a month to go to the NFL, I look at this guys history:
Coaching Experience
2012 - Florida Atlantic University (Assistant Coach/Running backs)
2010-11 - Montana State (Assistant Coach/Running backs)
2009 - Stillman College (Assistant Coach/Offensive Coordinator/WR)
2008 - Texas Southern (Assistant Coach/QBs)
2007 - Morgan State (Assistant Coach/QBs)
2005-06 - Booker T. Washington High School (TX)
I'm not seeing long term commitment or stability anywhere other than perhaps the last stint at FAU. Who knows, maybe being at a big program like UF will get him to stay put for awhile, if he proves out. Like I said, I trust in JMac.
