Not a bad surmisal to check out if you haven't yet looked @ the individual stats...
What you say might be so if you go all the way back to 1999...didn't recognize some names from that season...and they seemed to have a lot of rushing fumbles that year.
If you look @ the 20 players on the last chart of the thread, you'll see players like BenJarvus Green-Ellis that doesn't fit your theory.
He carried the ball over 500 times for the Pats...almost 600 total touches...zero fumbles...THEN he goes over to the Bengals for a few years and fumbles 5x.
Kevin Faulk is another one...he's fumbled the ball 25x in his career...including a playoff game. Before the 2007 season, he already had 23 TOTAL fumbles to his name.
2007 comes along and he only fumbles twice more thru 2011...and one of those was on a punt return.
Yeah, Welker fumbled it 6x as a Pat WR...but considering he had 762 touches...it's a pretty good "rate" to fumble only once at WR every 127 touches.
I'd say half of the players on that list started careers elsewhere ...Morris, Moss, Taylor, Amendola, Gaffney, Lloyd, Stallworth, Lafell, Evans ..most of them fumbled more elsewhere before coming to the Pats... (Moss had more fumbles elsewhere but a better fumble ratio with Pats)
A few of those ... Amendola, Lafell still with NE.
Other guys that went elsewhere...like Maroney and Woodhead...really didn't have that bad of a fumble rate either...similar to Welker's ratio...
Wow you really need to get a life.. BTW Ben Jarvis never fumbled At all till after he played for the patriots not pee wee not high school not in college. So I imagine you have some spreadsheet to prove the patriots did that too.
