Wow, isn't that a completely revised version of the facts.

First, Osweiller was given every chance in his four years with Denver to take the starting job from an aging injured Manning. He sat for 3 years and did nothing. Then in his fourth year he replaced Manning when he was injured but after teams figured him out he was a flop. 

Second, Elway offered Brock way more money than he deserved but Houston offered even more and ended up regretting the mistake. As a result, Brock flopped in Houston and they traded away his contract like a hot potato. 

Third, Brock ended up being cut by the worst team in the league with possibly the worst QB situation. Brock most likely would be out of the NFL but Elway threw him a bone when Paxton injured his shoulder. 

Fourth, Brock still isn't the answer in Denver. He will only play one or two games and then Denver will give Paxton a chance to prove his worth. But honestly don't expect much from any QB on this roster as the O-line needs fixing first.
