Between 06 and '11 he was the most feared left handed slugger in baseball. More feared than Joey Votto by quite alot.
He's 33 and plays in Citizens Bank. There is no reason to think that Howard can't return to being 35+ homers and 100+ rbi.
BTW he had an awesome spring along with Dominic Brown.
I don't think Howard will win the MVP, but to write off one of the finest power hitters of this generation before the season even starts is rather foolish imo
