Special contributor Matt Mosley answered questions in a live chat Friday. Here are some highlights.

Question: Teams always speak about drafting the best player available. The Cowboys are picking at their highest position since 1991. They have a crack at the top QB prospects they've not had for some time. Even if they're not committed to them as franchise QBs, might the Cowboys draft Goff or Wentz as trade bait? They could be worth up to 2 first rounders, the way mediocre QB's today are contractually valued.

Matt Mosley: If you take a quarterback that early, that's your future starter. Teams that have drafted and then traded QBs don't take them in the first round. You take them in the second or third round and then you play them just enough to get other teams a little excited. That's how guys like Kevin Kolb and even Matt Schaub end up making a ton of money. Matt Hasselbeck was drafted by the Packers all those years ago, if memory serves me correct. Ron Wolf liked doing that. If the Cowboys take a QB at No. 4, he will need to be the starter in the next 2-3 seasons.

Question: With KC's Hussain Abdullah leaving the NFL over concussions, how long do you think it'll take for a Cowboy to retire seemingly early over CTE concerns?

Matt Mosley: It's a great question. It makes sense that it's happening because players finally are seeing meaningful data. Jerry and Irsay can sit out there and talk about aspirin and sound like idiots, but these players are smart enough to see through all that. I think it actually sends a good message to the league when a player retires early. Hopefully it makes them even more serious about head injuries. But what's already started as the more parents and kids will decide at a young age that it's not worth the risk.

Question: Hitchens had the aura of a great up and comer, a steal in the draft, position flexibility and the hopeful comparison when the Cowboys drafted another LB in the mid-round last year. Then last season he disappeared and either I missed the articles about his regression or there wasn't much coverage. So what the heck happened?

Matt Mosley: I think he did a nice job stepping into a tough situation. It's just that he's not nearly as good as Lee or McClain. The Cowboys would like to keep looking for LBs who can line up next to those guys. Hitchens is a nice player, but I've seen him have a rough time taking the right angles. He's still young. He'll be in the league for a while. But not every LB can start for 8-9 years. He's just not that guy. Nice player, though. Can help you in a pinch.
