Beliichick started his coaching career in 1975 as an assistant with the Colts and worked his way up the ranks before becoming an NFL head coach in 1991 with the Browns. He spent 12 years with the Giants becoming a very successful defensive coordinator under Bill Parcells. Belichick was a big reason why the Giants won the SB in 86 and 90. Parcells never won a championship without Bellichick who had 16 years of coaching experience before landing his first NFL head coaching job. Garrett had less than 6 years of coaching experience before becoming the Cowboys interim head coach. Garrett has the least experience of any current NFL head coach. Ron Rivera is the second least experienced head coach and he had 15 years of coaching experience before landing the head coaching job in Carolina. The odds on Garrett becoming the next Belichick are slim and none. Belichick didn't become what he is until 2001 when Brady took over for Drew Bledsoe. It took over 26 years for Belichick to be considered a great NFL head coach. It could take another decade just for Garrett to develop into a decent head coach. He still hasn't learned how to manage a clock that could take another 5 years. He's going through on the job training teams are suppose to develop players not their head coach. You're suppose to hire a head coach who's ready to be a head coach not one you have to teach on the job. If Jerry wanted Garrett as his head coach he should have kept him as an assistant under a competent head coach for a few more years so he could continue to learn and would have been ready to be a head coach. Garrett is in over his head it's obvious to everyone and it's making Jerry and the organization look foolish. How embarrassing it must be for Jerry to constantly have to answer questions about the competence of his head coach and his inability to manage games.
