I put the entire Brown crap-show on Tomlin. Had he managed his players better and avoided the favoritism and fawning that he obviously pushed Brown's way, he likely would not have been the complete basket-case he turned into.
This year, Tomlin has got to demonstrate that he can coach the team to an upper-tier performance when, for the first time in his ENTIRE career he doesn't have the entire offense stocked with ringers. He's got 1 H.O.F. guy now and one up and coming receiver. Fortunately he still has one of the best offensive lines in football, but he's lost the coach that built, molded and coached up those guys. So it will be very interesting to see how that unfolds.
Tomlin, in my opinion, has no excuses whatsoever. He's added talent to the defense. That is his area of specialty so I expect the defense to start pulling their own weight plus some this season. Fans cannot reasonably expect the offense to put up the kind of numbers they have in the past. That is completely unrealistic. Now they need to be a more ball-control, get a lead and hold it kind of team. That is entirely on Tomlin. 100%
