Byline: Jennifer Toland COLUMN: Pats Notes SMITHFIELD, R.I. -- Offensive coordinator Charlie Weis, who on Tuesday addressed the New England media for the first time since undergoing gastric-bypass surgery in June, made an appearance at yesterday's afternoon practice session. He arrived at the field in a motorized cart. Weis gave no precise timetable for his full-time return to the field. He has been viewing film and has attended meetings and fullback Marc Edwards said his presence, in most ways, is still being felt. ``You don't hear his boisterous voice bellowing out there,'' Edwards said, ``but Belichick has really taken to the offense and Charlie has met with the offensive coaches and put his input in, so his influence is definitely still there.'' Belichick said Weis has had daily interaction with Brady since returning part-time on Monday. Belichick gave no indication of Weis' expected full-time return either. ``Whenever the medical people clear him to be on the field it will just be for a limited amount of time and that will gradually increase,'' Belichick said. ``That's the way it's been explained to me and that's the way I expect it to go, assuming there are no setbacks. When he starts out he's not going to be actively out there coaching guys. It's more of an observation type thing and then that will, I think, move forward to where he does get a little more involved. We'll just have to take that as it comes.'' Three's company for Pats Letting Tom Brady stick around as the team's fourth quarterback two years ago obviously paid off big time for the Patriots. It was a wise investment and a roster spot well-taken, despite the fact Brady was inactive for 14 games that season. With Brady, Damon Huard and Rohan Davey, the Patriots are the only NFL team with just three quarterbacks in camp this season. The average number of quarterbacks on a roster is 4.2 and six teams -- Denver, the New York Jets, Cincinnati, Chicago, Minnesota and Seattle -- each opened camp with five. The Bengals, Bears and Seahawks are now down to four. ``If we really thought that we had quality at the fourth quarterback spot we would keep him,'' Patriots coach Bill Belichick said yesterday after morning practice at Bryant College. ``If we could find the right guy we would still do it, and we would have to find a way to get him some reps.'' The Patriots carried four QBs for most of the 2001 preseason -- Brady, Drew Bledsoe, Damon Huard and Michael Bishop, who was...
