Edkamen ... Tucker has not improved every year
Tucker has been great all along... shareing equally with EW and WJ last year in carries. Plus the only reason he had less ypc the past 2 years, was due to his more frequent use than the other 2 in short yardage downs. His FRHS year in 2009, when he led the team in ypc(6.4),the Sr. Turner was the short yardage guy.
He had a couple of fumbles his soph/2010 year, which cut his CPG back the last part of that season, except when EW went down early in SDSU game and Tucker had 22 carries for a 131 yards. The last 3 seasons... never felt our offense less than, when Tucker was in... at any time.
Since we've averaged over 30 RB carries per game the past 3 years... are you sure you "don't want to see him carrying 15 times a game"; so 12-13 only.?. Then, how do you want to split the other 18 to 20 carries. For now, until we see what we have with Dean and Catalon ... 15 to 20 carries for Tucker is my guess, plus he's always been a very good reciever and the best blocker in the backfield.
Cheers !
