Concerned About Colston Contract Extension

If anybody thinks we are not gonna be able to keep Colston, your crazy, he is the least of my worries, i'm more worried about keeping Smith....Colston is a LOCK to come back, a bout a sure thing as I can imagine, and I have no link to back me up....he has done everything and more and is a professional, teams arent scared to throw money at those type players....and we have managed the cap very well in anticipation of this....its just the matter of when, that I think has alot of people worried...or anxious should I say.
