I am an avid chess player, but not really that great, so my rating is pretty much beginner. But I like the rating system, as you get various +'s and -'s based on who you play I thought I would apply it to our head coaches (except for Noll, because I didn't see all of his playoff games). I went through all the games I remember and tried to assess the performance and notes from what I remember. I'll max each game at + or - 10 and then add the score divided by the number of games x 10. 100 is a perfect score which no one would ever get. Lol Also, these are my humble opinions, so not trying to influence anyone. This also assumes the Patriots were legit (even though I know that they cheated the Steelers multiple times). Cowher 1. 1992 Div vs Bills L 3 - 24. Cowher 1st time in playoffs vs defending champs. (-4) 2. 1993 Wc @ Chiefs L 24-27 OT facing Joe Montana on the Road. Up by 7 late. Montana Magic. (-2) 3. 1994 Div vs Browns W 29-9 facing Bill Belichik, 3rd Win vs Browns same season (+6) 4. 1994 AFCC vs Chargers L 13-17 facing Humphries/Bobby Ross, Meltdown after up 10. (-10) 5. 1995 Div vs Bills W 40-21 Bills on the downside of their run, game got close late, good win. (+4) 6. 1995 AFCC vs. Colts W 20-16 Much closer than anticipated, Could have easily lost. But a win. (+6) 7. 1995 SB vs. Cowboys L 17-27 We all know this one. Good effort against a dynasty team. (-2) 8. 1996 Wc vs Colts W 42-14 Was closer than score at times, Wore down the colts with Run. (+2) 9. 1996 Div @ Patriots L 3-28 Ugly game, no offense with Tomczak. No answers on D for Martin/Bledsoe (-4) 10. 1997 Div vs Patriots W 7-6 Tough defensive struggle, Really good win vs Parcells. (+5) 11. 1997 AFCC vs Broncos L 21-24 Disappointing Loss. Kordell was a turnover machine. Elway and TD too much. Can't be too hard on Steelers facing HOF QB/TE/RB. (-4) 12. 2001 Div vs Ravens W 27-10 Solid Win vs Divisional Opponent, No surprises here. (+4) 13. 2001 AFCC vs Patriots L 17-21 Expected to Win this one, Kordell struggles mightily. (could have been a cheating game, but otherwise felt like 1994 vs SD again). (-10) 14. 2002 WC vs. Browns W 36-33 Great comeback in this one. Tough to beat a team 3 times in a season (+5) 15. 2002 Div @ Titans L 31-34 OT Great game, back and forth, McNair/George too much. Questionable call late gives Titans 2nd kick to win (-3) 16. 2004 Div vs Jets W 20-17 Jets Kicker gives away game, Very lucky to get this one. (+4) 17. 2004 AFCC vs Patriots L 27-41 Brady/Belichik at the height of their Powers (cheating). Pittsburgh overwhelmed early, showed fight, but succumbed. (-5) 18. 2005 WC @ Bengals W 31-17 Start of We Dey! Unfortunately Carson goes down very early. Could have been a tougher matchup. (+3) 19. 2005 Div @ Colts W 21-18 Huge Win vs HOF Manning/Dungy combo. Idiot Kicker misses to tie. SIGNATURE Win on the Road when expected to lose. (+10) 20. 2005 AFCC @ Broncos W 34-17 Expected the win vs Plummer, tough venue, but Broncos had no answers after beating Patriots week before. Very solid win. (+8) 21. 2005 SB vs Seahawks W 21-10 Defense shuts down Seahawks. Did have help with some favorable calls. Big Ben plays poorly. Not a suberb win, but a win. (+8) Cowher ends up with +21 divided by 21 x 10 = a 10 rating. Tomlin 1. 2007 WC vs Jaguars L 29-31 Can't stop Garrard, 2nd loss to Jaguars in 3 weeks at Home. 1st playoff for Tomlin. Garrard's only playoff win. Mulligan (-2) 2. 2008 Div vs Chargers W 35-24 Good Win vs Rivers, but Chargers were average all Season. No surprises (+4) 3. 2008 AFCC vs Ravens W 23-14 Polamalu seals up the win! 3rd Win vs Ravens this season. Great win, but not enough to be Signature as it was in Pittsburgh. (+8) 4. 2008 SB vs Cardinals W 27-23 Not sure why it got so close at the end. Warner/Boldin/Fitzgerald keep the Cardinals in contention. Signature drive by Big Ben but not a Signature win in my opinion. (+8) 5. 2010 Div vs Ravens W 31-24 Big Comeback after halftime for Steelers. Antonio Brown makes great catch to set-up go ahead TD. Solid win vs Divisional opponent. (+6) 6. 2010 AFCC vs Jets W 24-19 Sanchez makes it close towards end. Antonio Brown with another clutch catch to seal the win with a first down. Not a spectacular win. Jets did a favor by beating Patriots in Divisional round. (+6) 7. 2010 SB vs Packers L 26-31 Steelers come out flat, down big early, nice comeback. Mendenhall fumble swings momentum. Big Ben set up for signature drive, but 4 and out seals it. (-6) 8. 2011 WC @ Broncos L 23-29 OT Can't prepare for Tebow's attributes. Pretty Bad Loss. Down 6-20 at Half. Nice comeback, but no defense at the end. Tim Tebow's only playoff win. (-8) 9. 2014 WC vs Ravens L 17-30 No offense/no defense. Bell out after injury in week 17. Flat game vs Divisional opponent. (-6) 10. 2015 WC @ Bengals W 18-16 Bengals give Steelers game with penalties/TO at end of game. Pittsburgh blows big lead. Should have lost this one. (+2) 11. 2015 Div @ Broncos L 16-23 Big Ben playing hurt, No AB, no offense. Key turnover by RB during crucial drive. Broncos defense too much as Manning manages game. (-4) 12. 2016 WC vs Dolphins W 30-12 Comfortable win vs Matt Moore and average Dolphins. Nothing here to see. (+2) 13. 2016 Div @ Chiefs W 18-16 Boswell is the MVP. Great win on the road. Would have been Signature if Mahomes existed. Beating alex smith should happen. (+7) 14. 2016 AFCC @ Patriots L 17-36 Terrible performance in "statement" game. Steelers didn't show up. Bell injured but would not have mattered. No chance against the Cheaters. (-8) 15. 2017 Div vs. Jaguars L 41-44 Terrible performance before "statement" game. Steelers didn't show up. No answers for Blake Bortles. Signature loss (-10). Tomlin is a -1. Divided by 15 x 10 = -0.67 rating So, I would have to do more coaches to get an idea of what all this means. But to say that Tomlin is anywhere near Cowher as a coach is ridiculous. I know most of you won't read this, but you can do your own evaluation. I personally saw every one of these game in detail except for the 7-6 win vs Patriots. Feel free to comment about my system/rating. I tried to be fair and impartial. Mind you, the Patriots were cheating during Cowher's stronger runs, so who knows what that did to the ratings.
