I've already stated. Milton was less consistent, especially in pressure situations. That was compounded by WRs with the dropsies.
To simply point at Milton's arm strength and say that that makes it more of a headscratcher that UT's offense was less explosive is to not have watched Hooker and Milton. I watched every play EXPECTING Hooker and the WRs to do something amazing. I learned to expect Milton to miss a pass, throw it high, skip it in the dirt, throw it late, throw it like a canon for eight yards. Or, for the WRs to drop it when it hits them in the basket.
Hooker could throw it into tight coverage over the middle for 15 yards when we needed 12 to keep a drive alive. Milton was generally throwing a screen or overthrowing down the sidelines. It would be interesting to see 3rd down conversion stats between Hooker/Milton. That'd probably be the best insight into which QB was driving the offense.
Milton's stats weren't really as close to Hooker as you make it out. But the way he built the stats were far different than Hooker as well.
