comparing to caddy's rookie year is dumb
caddy: 16 plays 10-20 yards, 2 runs of 30-40 yards... 1 yard 40+
the entire season
All Day: 16 plays 10-20 yards, 2 plays 30-40 yards ...
4 plays over 40 yards, so far!
All Day- 6 TD 30 first downs in 6 games
Caddy- 6 TD 51 first downs in 14 games
Caddy 1178 yards rushing 81 receiving
All Day- 670 rushing, 178 receiving....
If all day plays 14 games like Caddy...projected 1563 rushing , 415 receving
if All Day plays 16 games 1786 rushing, 474 rushing= 2260 yards which is close to Tomlinson's best years where LT had 2300+ yards, Marshall Faulk who had 2400 yards, and Preist's best year of 2287 yards
Rookie seasons: total yards
Faulk 1810 yards total
LT2- 1630 yards
Dickerson 2212 yards-
Barry- 1752 yards
Emmitt- 1165 yards
Caddy

1259 yards
Sure projecting is risky business... All Day could get hurt tomorrow (hope not)... but the talent he has is immense, a once in a decade or more talent... he could easily rival LT2 and is one of the rare people who (at this early stage) we could imagine entering the discussion of best RB ever with Barry Sanders, Jim Brown, Sweetness, etc
So to come back to the point.. in a dynasty, All Day is number one and only LT is a reasonable guy to trade for (because LT has the resume which All Day hopes to have in a few years).. but All Day is much younger... Fantasy Football is about luck and taking risks... IMHO holding All Day is the least risky move UNLESS you get a really dumb offer proposed to you (like LT2 + Calvin Johnson in dynasty or something like that)
In redraft he isnt a sell high... most people still wouldnt trade him for anyone but LT, maybe Parker if you're lucky
