10:24am: The Eagles will submit an official request to talk to Koetter as well, according to Alex Marvez of FOX Sports.com.
The Buccaneers, meanwhile, have already spoken with Koetter about taking over as head coach, but a formal interview has yet to take place, Roy Cummings of The Tampa Tribune tweets. That interview could take place today.
9:16am: The 49ers requested permission to interview Koetter on Tuesday and still haven’t gotten an answer back, Adam Schefter of ESPN.com tweets. That could be an indication that Koetter already has the Bucs job in the bag.
6:38am: The Buccaneers will conduct a head coaching search, but their next hire might already be down the hall. Even though the team will go through the process of combing through head coaching candidates, it appears that things are pointing towards a “coronation” of offensive coordinator Dirk Koetter, Rick Stroud of the Tampa Bay Times tweets. Koetter is in play as a candidate for the Dolphins vacancy and as Miami’s interest grew, Bucs ownership felt that it had to move quickly in order to keep its highly-coveted OC from jumping ship (link).

As Pro Football Rumors’ 2016 NFL Head Coaching Search Tracker shows, Koetter is among the baker’s dozen of known candidates for the Dolphins’ head coaching job. The two sides have yet to formally set a date for an interview, but Tampa Bay felt that things were heating up between their OC and South Florida’s other football franchise. Presumably, the Bucs are happy with the work Koetter has done with No. 1 overall pick Jameis Winston and losing Koetter could be detrimental to his development.
Under Koetter’s guidance in 2015, the Bucs averaged 375.9 yards per game, good for 5th in the NFL. Tampa Bay also placed 5th in rushing yards per contest with 135.1 yards on the ground per game. With Koetter calling the plays, running back Doug Martin managed to get back to his old form while 2014 third-round pick Charles Sims made great contributions as a pass-catching option.

So was Smith fired because of a bad job or because they think Koetter is a better long term solution?
I think they feel Koetter is the better long term coach
I guess they missed Koetter being mediocre in college. Just a hint to the Glazers, coaches don’t get better when they have to do that job at a tougher level, lol.
