Eric has I believe in the past mentioned Sewak doing a bad job of recruiting and having in particular been a neglectful host when recruits had visited campus a time or two.
We all know that CPJ intimated having had a serious sit-down and evaluation with CMS after last season. Of course, CPJ surely does this with all his "direct reports" every year. But I remember his having made it very clear that he was extremely displeased with last year's OL performance (or maybe even OL performance since losing the 2nd assistant coach who originally helped at that position?). Anyway, CPJ retained CMS but brought in Rychleski, in part, to help on OL.
Given results so far that may be the only change that was needed. Because as far as the recruiting aspect goes look at what is said about Sewak in today's Carvell piece on AJ Gray:

I was never in a position to proffer a strong opinion on CMS's capabilities or efforts as a GT coach. But
if CPJ lit a fire under him and
if that was necessary to get better results from CMS on this year's recruiting trail and
if getting him help in terms of position coaching the OL is what was needed to see this year's positive gains than three "hip-hip-hooray's" to CPJ and a hearty "atta boy!" to CMS for stepping up with OL improvement this year and doing so well at getting after AJ Gray. Maybe this offense is so complex at the OL that CMS simply could not handle it all by himself plus fulfill his duties recruiting as well without having a second OL coach?
Tech simply cannot afford to ignore any "weakest links" as far as coaches go on the recruiting front. There are way too many obstacles to overcome to not have everyone giving their best effort and
always seeking to improve.
