Boy I'll tell ya what...
Chief clearly didn't prepare anymore. He messed up player names and facts and most of the time knew nothing about the opponents. Sure it was fun to listen to his rants but it was not a professional analysis of the game. I mean compare him to the color guy San Jose has (or most of the other teams), they were worlds apart.
Engblom on the other hand is a bit too unbiased. That sounds like I'm an idiot but let me explain. It's a local broadcast and you'd expect some of the guys to at least root for the home team. It's pretty apparent that he was doing national coverage on ESPN, VS and NBCSN. I think before the Lightning he did one season as the color guy for the Jackets and other than that he always had to be the impartial color analyst on national TV.
Rick rarely shows that he's rooting for the Bolts in his heart so with Chief gone the broadcast feels a little bit too impartial and "clean". In the end Chief didn't provide much depth regarding the game but he was the entertaining factor. The guy has character, no doubt, and we all loved his cringy comments and were playing the Chief Drinking Game during games (man the hangovers were bad). But if I had the choice I'd go with Engblom over Chief, just because I want to hear them discuss the game, the strategic aspects, what is said on the benches and on the ice and not listen to a guy who half-way into his sentence stops talking while Rick awkwardly tries to cover for it.
