That sounds a whole lot like Mario Williams. Supreme talent but lazy ass character. Or David Carr for that matter. If Montgomery ends up like this, at least the Texans only wasted a 3rd pick rather than the #1 overall. I say that while acknowledging the opinion that he was probably the best pick the Texans could've made at #1 in the '06 draft.
Coming in as a 3rd round pick will (hopefully) be humbling for the man. Watching such players as Watt and Cush go through their conditioning programs and seeing their dedication to film study and how they go about their business as a pro, will hopefully open his eyes as to what needs to happen to be successful at the NFL level. If he gets his act together and buys into what Watt and Cush preach, he could be a monster. If he doesn't, he's a washout 3rd rounder in a couple of years. Won't be anywhere near the 1st or the last.
