Green Bay fan perspective...
"When the Packers drafted Brian Brohm in the late second round last year, there was a mini surge in BROHMania. Predictions flew that Rodgers was no good and that the Packers took Brohm because they didn't have confidence in Rodgers... according to posters on this site and others, Brohm would be the starter in GB before the end of Rodgers' first disastrous season. Only, Brohm couldn't beat out Matt Flynn, taken in the 7th round of the same draft. Packers fans, and no-doubt Packers coaches, watched with amazement as Brohm could not grasp the pro game or pro speed. He appeared to hesitate on every throw, suffered from happy feat, overthrew receivers frequently and seemed unable to throw any kind of spiral. He wound up buried on the depth chart.
This spring, there was no talk of Brohm replacing Rodgers, but there was considerable excitement that Brohm might be able to come out, shake of an unexpectedly poor rookie season and re-establish himself as a potential NFL starter. Visions of Matt Hasselbeck returned and there was optimism that Brohm could at least wind up as solid trade-bait. But by the end of camp, he had shown no measureable improvement from the previous year. Some started saying that he'd be a good candidate to be released by the Packers. When that did happen, not one team of the other 31 claimed him. The Packers signed him to the practice squad, but that should not be confused as a sign that the Packers thought he was likely to turn it around. Had they had that opinion, they never would have cut him. Brohm made sense on the practice squad only because he already knew the Packers offense, not because they envisioned him as a starter. In fact, due to injury, the Packers had plenty of opportunity to elevate Brohm, but instead chose to sign such big names as WRs Jake Allen and Biren Ealy.
The fact that Brohm sat on the Packers practice squad for 2 months before being signed by an NFL team tells you all you need to know about his chances of making it as an NFL starter anytime in the immediate future."
