Brown will probably make those numbers, but not Holt... Too many weapons for the Rams for him to catch 93 balls and 10 TDs. I'd say 65-70 for 1000 and 7-8 TDs. Then again, I hate predicting performance numbers.
Holt in 1999 had over 1600 yards and 6 TDs. Last year, he had over 1300 yards with 7 TDs. Last 2 years he's had over 80 in each. So my prediction would be around 1400 yards, 8 TDs and around 85 receptions. I'd expect the same as you for tim brown.
