It's considered a lock that the Panthers will spend the first overall pick in 2011 on QB Andrew Luck if the Stanford star declares for the draft before the Jan. 15 deadline. Quarterback is a need for the Panthers, as rookie Jimmy Clausen has struggled, but the team has other glaring voids to fill on its roster. For instance, one team observer said addressing a bad situation at defensive tackle should be a high priority. After cutting DTs Maake Kemoeatu and Damione Lewis last offseason, the Panthers, who scaled back spending in advance of a potential lockout in 2011, didn't invest much in finding replacements for them in free agency and didn't spend a draft pick on a defensive tackle. Carolina only has one D-tackle — undrafted rookie Andre Neblett — under contract through next season. Without any top-tier talent, it has been one of the Panthers' weakest spots and there likely will be quite a bit of turnover at the position for the second consecutive year.
