i don't buy the idea at all being posted in this thread that richt could not find anyone better than banda and patke for this job.
coaches across the country know the defensive talent that is already on the roster, and is of course in the area for recruiting. the guy who was just the DC here got what is probably one of the best non-power 5 jobs in the country: temple's last 4 coaches (geoff collins, matt rhule, steve addazzio and he who shall not be named) all graduated to power 5 head coaching jobs. on top of all that, manny was likely getting paid $1 million+, and despite what people on this board say or want to believe, richt is not going anywhere. all of that is to say that this was obviously a very attractive DC job, offering stability, good money, and the sort of talent and visibility that can get you a good head coaching job if you succeed.
maybe richt's first choice wasn't available -- manny diaz was his second choice the first time around, after all -- but my reading of the situation is that, instead, richt believes banda and patke are the best choice for the job. i'm not saying i agree with him -- i have no idea if banda and/or patke are capable of doing the job -- just that, logically, this was a job people would want, and that richt turned down suitors from the outside.
to me, this is a volatile hire with a high ceiling and low floor. the upside is that banda and/or patke are rising stars in the coaching business who were kept in-house and will keep the defense humming until they're inevitably poached by schools with more money or better jobs. the downside, of course, is that they're not ready to handle this and the defense suffers. we shall see.
